Comment:

 Do you think you could get an profile from 'perf' or 'oprofile'?  The set
 of library functions that ltrace is reporting suggests that might not be
 so hard to fix, but to do so, we'll need some way to figure out what place
 in Tor is spending so much of its time in string processing for this case.
