PHP's sleep & usleep() functions can be used to bypass set_time_limit() and allow a script to sleep forever thus taking up a webserver thread/process for an unlimited period of time.

Pretty much documented and by design.  I don't see anything that needs fixing here.

max_execution_time limits use of CPU time,
not real time, sleep() and usleep() don't use
