To prevent other simultaneous calls to save the configuration,
ps_setup_save() acquires an

a timeout parameter to indicate how many seconds to wait if
the lock already exists (which indicates that some other

This procedure disables binary logging during its execution by

That is a restricted operation, so the procedure requires
