+    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.
