LuaSandbox::setCPULimit — Set the CPU time limit for the Lua environment
Sets the CPU time limit for the Lua environment.
If the total user and system time used by the environment after the call to this method exceeds this limit, a LuaSandboxTimeoutError exception is thrown.
Time used in PHP callbacks is included in the limit.
Setting the time limit from a callback while Lua is running causes the timer to be reset, or started if it was not already running.
On Windows, the CPU limit will be ignored. On operating systems that do not support CLOCK_THREAD_CPUTIME_ID, such as FreeBSD and Mac OS X, wall-clock time rather than CPU time will be limited.
Limit as a float in seconds, or false for no limit.
