emacs is now using 98.1% of a P4 3GHz while apparently doing
nothing.  It is continuously using more than 50%.
Here's the output of top:
26022 rmel  39  19  104m  37m  10m R 98.1  1.9  51:01.88 emacs

One of my co-workers is logged into my machine running emacs and
it is his session that is hogging the CPU.  I just went and talked to him
and he wasn't doing anything in that session.  He had left the emacs
code browser open, so I asked him to deactivate it to see if that would
make the problem go away.  It did not.  Is there a way to get emacs to
profile itself while this problem is happening so I can provide some
more useful debugging info?

Thanks,
          David
