Funny story about that...
I wanted to profile some code of mine, and a colleague recommended the
'hotshot' module.
It's pretty easy to use: there are functions to start profiling, stop
profiling and print results.
So I added the function calls and ran my code.... and it took a really
long time. I mean a REALLY long time. In fact I eventually had to kill
the process.
I briefly wondered if my coworker was playing a prank on me... then I
realized that I had neglected to call the function to stop profiling!
So when I went to print the results, it was still profiling... endlessly.
(Okay, maybe it wasn't that funny.)
