Sorry, that was a bogus trace with some old stuff in it.

The real profile was this one.

	102343   73.1377  libc-2.6.so              libc-2.6.so              _wordcopy_bwd_aligned
	3573      2.5534  git                      git                      cache_name_compare
	2328      1.6637  git                      git                      index_name_pos
	...

which matches the rest of my emails.. (the "73%" is actually really 
supposed to be about 95%, but I had X running and doing stuff at the same 
time, so it was only 73% of all the other CPU activity that was going on 
over the time I profiled).
