Fix get args construction when there are multiple lists on the page It is now possible to go back and forward through the liast, and specify the limit (both offset and limit can be done per list). The JS driving the list boxes is buggy, if visiting an url like: http://localhost:8080/notification/list?limit_0=10 And then change the limit in the second checkbox, it directs to: http://localhost:8080/notification/list?limit_1=25 Whereas it should redirect to: http://localhost:8080/notification/list?limit_0=10&limit_1=25 The logic _does_ work properly when the limit of the changed list is already present in the url.

    '''
    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.
