Hotshot does do that - I tried it about a year ago and the resulting data took about 30 minutes for KCachegrind to chew on but it did generate output.

I'm certainly curious to see the profile navigation. I seem to recall
that somebody has written a nice GUI for analyzing Python profiling
results but I don't remember where I saw it. Personally I haven't had
reason to do much with profiler data besides sort the data a couple
different ways and display the top 10 or 20 routines by time, cumulative
time, or number of calls.

I seem to remember that Hotshot profiler was able to output it's data in
Vallgrind format. Calltree could then suck up this data. Calltree (or
KCachegrind) is a visual tool similar to Rational Quantify, which you
could use to visually track down performance issues. See
http://kcachegrind.sourceforge.net/cgi-bin/show.cgi

Caveat: I have not tried this myself.
