Attached are 2 Modules/_lsprof.c files, one for Python 2.5.2 and 2.6a1 
and the other for Python 3.0a3.  Discard the previously posted one.

Both contain the same enhancements to use the high-resolution timer 
where available.

These versions catch wrap around of the timer and clock and adjust 
accordingly.  In the hpTimerUnit function only and not for profile 
times.

Lastly, instead of malloc and free functions PyObject_MALLOC and 
PyObject_FREE are called making profiler memory usage the same as for 
other objects created.
