##
## Test the Performance Schema-based implementation of SHOW PROCESSLIST.
##
## Verify handling of the SELECT and PROCESS privileges.
##
## Test cases:
##   - Execute SHOW PROCESSLIST (new and legacy) with all privileges
##   - Execute SELECT on the performance_schema.processlist and information_schema.processlist with all privileges
##   - Execute SHOW PROCESSLIST (new and legacy) with no privileges
##   - Execute SELECT on the performance_schema.processlist and information_schema.processlist with no privileges
##
## Results must be manually verified.
