'''
Handler that uses hotshot to store profile data.
Stores profile data in PROFILE_DATA_DIR. Since hotshot has no way (that I
know of) to append profile data to a single file, each request gets its own
profile. The file names are in the format <url>.<n>.prof where <url> is
the request path with "/" replaced by ".", and <n> is a timestamp with
microseconds to prevent overwriting files.
Use the gather_profile_stats.py script to gather these individual request
profiles into aggregated profiles by request path.
