Hello,

=20

I have a process with several threads - the main "worker" threads
typically use < 20% CPU - but after upgrading to a new version they're
now using > 90% cpu.  I'm trying to determine what function these
threads are performing that's requiring so much more cpu.  Is it bad
code? I bug in a library I linked against?  What?

=20

I've tried gdb with list, info threads, info stack, bt full.  I can make
sense of some of it.  I guess what I'm hoping for is something like
"top" at the thread level, such that functions that thread perform are
sorted highest util (time/whatever).

=20

TIA for any help!
