You can now again use requestprofiler with python1.5.

Timed modes no longer require a start and an end.  If a start and an end
is not specified, the start time will be considered the first time
encountered in the set of log files and the end time will be considered
the last time encountered.

The default resolution for timed mode is now 60 seconds.
