It might be me, but I find it a bit odd that you didn't do anything with
this fix.  I'm sure that for each alternate profiler posted on SF there
are ten half-finished ones on somebody's box.  The problem of hotshot
producing slightly wrong data is not new, and in hindsight the
discrepencies only became larger in 2.4 with the introduction of new
tracing events (C function calls). 

At this point I'm interpreting your mail as saying that you don't really
mind if hotshot is in the standard library or not, because you are using
your own fixed version anyway.  Nobody is proposing to wipe out hotshot
from the face of the planet.  Sorry if I sound offensive, but I'd rather
hear the opinion of people that care about the stdlib.
