Make sure the user edit form has the complete mail adress in the user account field when opened. Replace confusing id field in form with email field. Editing the email adress of an existing user will still result in an error but that should be fixed soon. Patch by: Lennard de Rijk Review by: Pawel Solyga

    '''
    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.
