 I frequently want to know profiling information for web servers in
 production. Unfortunately there doesn't seem to be a way to trigger this
 without stopping the program, which might annoy my users.

 My ideal would be to able to call "dumpProfile :: Filename -> IO()" and
 then call that from a timer thread.
