Subject: [Code-Crunchers] a simple race condition and how you'd solve it
Message-ID: <4A4D4FF3.8070101@linuxbox.org>

A friend recently demonstrated on his blog a simple race condition he 
encountered. He also challenged folks to solve the problem.

There's an interesting discussion in the comments which is worth a quick 
read.

Also, maybe someone here will come up with a cuter idea?

Posted my proposed solution in the comments, but will probably take a
while to be moderated.

Basically, you just need to check if you should still be computing,
and, at the end of computation, if your data is still "wanted".
