"temporary hack"

Another excellent search is "don't know why this works"

This should work http://www.google.com/codesearch?hl=en&lr=&q=%22this... or this might work http://www.google.com/codesearch?hl=en&lr=&q=%22this...

Searching for various expletives is always fun, too.

Try "kludge". I never write "temporary hack".
