I don't think so.  It has something to do with processes.
Notice:

#5  0x08175641 in Faccept_process_output (process=162478740, timeout=0,
    timeout_msecs=137362409, just_this_one=137362409) at process.c:3778

And today, while I was working a lot with eshell and CVS, I got
another hang...  This time I find read_process_output_call on the
stack...  Weird.

When I continued today's crash, waited a while, and interrupted it
again, I got a huge stack of mark_object stuff, so I think that's
something else...  If only I know more about debugging Emacs.
