#     SELECT ... PROCESSLIST/SHOW PROCESSLIST                          #
#                                                                      #
# Note(mleich):                                                        #
#     There is a significant risk to get an unstable test because of   #
#     timing issues.                                                   #
#     Example1:                                                        #
#     1. Disconnect connection X                                       #
#     2. Switch to connection  Y                                       #
#     3. SHOW PROCESSLIST might present a record like                  #
#           <ID> <user> <host> <db> Quit 0 cleaning up NULL            #
#        or even a row where connection X is without                   #
#        "Quit" or "cleaning up".                                      #
#        That means our SHOW PROCESSLIST can come too early.           #
#     Solution:                                                        #
#        Close the connections at the end of the test.                 #
#     Example2 (2008-08-14 again observed):                            #
#     1. connection X: SHOW PROCESSLIST/GRANT ... etc.                 #
#     2. Switch to connection  Y                                       #
#     3. SHOW PROCESSLIST might present a record like                  #
#        <ID> <user> <host> <db> Query TIME cleaning up <command>      #
#        <ID> <user> <host> <db> Query TIME writing to net <command>   #
#        Problems happens more often in case of slow filesystem!       #
#     First Solution:                                                  #
#        Insert a dummy SQL command where the cleanup is most probably #
#        fast before switching to another connection and running       #
#        SHOW/SELECT PROCESSLIST.                                      #
#        Suppress writing to protocol by assignment to $variable.      #
#        let $my_var= `SELECT 1`;                                      #
#        Even the 'SELECT 1' was in some cases in state                #
#        "writing to net".                                             #
#     Final Solution:                                                  #
#        --real_sleep 0.3                                              #
#        This value was at least on my box sufficient.                 #
#        Please inform us if this test fails so that we can adjust     #
#        the sleep time better or switch to poll routines.             #
#                                                                      #
#     Storage engine variants of this test do not make sense.          #
#     -  I_S tables use the MEMORY storage engine whenever possible.   #
#     -  There are some I_S table which need column data types which   #
#        are not supported by MEMORY. Example: LONGTEXT/BLOB           #
#        MyISAM will be used for such tables.                          #
#        The column PROCESSLIST.INFO is of data type LONGTEXT          #
#           ----> MyISAM                                               #
#     -  There is no impact of the GLOBAL(server) or SESSION default   #
#        storage engine setting on the engine used for I_S tables.     #
#        That means we cannot get NDB or InnoDB instead.               #
#                                                                      #
# Creation:                                                            #
