Details:
To catch infinite loops or any kind of very slow script, we can limit script
execution time. There should be something that interrupts script execution so
that it can't hang the server forever (writers of buggy scripts will be
thankful).
A lua debug hook is installed to be invoked every 10000 executed lua
instructions. The limit of 5.0 seconds of CPU time is a very high limit. It
applies to all script function calls individually, including script load
time, script callback execution, etc.
Proposed for 2.2 and trunk
An easy way to make an infinite loop in lua, for testing purposes, is 'while
true do end'.
