Modified Files:
Profiling.cpp
Log Message:
Optimization: saveProfile() is now a little gentler.
>From now on, saveProfile() generates a single file per process, not a file
for each request.
This makes profiling data merges quite faster, provided that saveProfile()
is called once per process (preferably with atexti(saveProfile);).
