Xorg crash in PlayReleasedEvents with Sawfish when using keyboard-

Bug description:
Binary package hint: xorg
Ever since upgrading to natty a couple days ago, I've been having
problems with Xorg crashing. I got a traceback (already attached,
gdmlog1), which suggested something related to pthreads, so I tried
disabling hyperthreading and all but one core in BIOS. This reduced
the frequency of crashing from about once per 10 minutes to once per 2
days. I don't know if it's specific to the intel driver, or if it is
a more general issue.
As far as steps for reproducing the issue... I'm not exactly sure. This is
a description of a typical session:
1. Log in via gdm. I'm using sawfish, with a custom Xsession.
2. Start a few programs. I ran xchat, chrome, midori, a few instances of
dillo, and a few instances if urxvt (client/server mode, not independent
instances).
3. Trigger a few window redraws, by changing desktops or moving windows
around. I triggered these actions via key shortcuts, generally a few times in
a fraction of a second.
Result: Once in a while, step 3 will cause an Xorg crash. The
frequency increases quite a bit with SMP enabled (2 cores + HT, so 4
logical CPUs).
