  I'm new to Django and have some code in my views.py like this: try: myfunction() except: assert False, sys.exc_info()[0] This is very helpful because I get an email with lots of useful info if there's an error.

• Setting timeout for embedded Lua

  I have embedded Lua in a C/C+= application. I want to be able to set a timeout value to prevent getting trapped with badly written scripts that can result in infinite loops (or even string searches that take an infinite time to complete). Basically, I want to be able to set a time interval and if the script fails to complete running at the end of that time interval, I want to be able to kill the Lua script engine (gracefully, if possible). Anyone knows of best practise way to do this?
