Comment:

 One reason this is annoying is that it means you can't have a manager
 thread running code (which you have no reason to believe won't go into an
 infinite loop or generate an infinite amount of output) with a timeout.

 For example, lambdabot can't just use something like the timeout function
 above to ensure its modules don't go into an infinite loop. Another
 example is not being able to give up and return a bad result if you run
 out of time in something like the ICFP contest.
