# 1. Status variable values are consistent with corresponding server events.   #
# 2. Status variable values are consistent across session, thread, account,    #
#    host, user and global tables.                                             #
# 3. Status totals for user, host and account are retained after related       #
#    threads disconnect.                                                       #
