Re: Emacs seems awfully unstable on OS X lately

[Harald Hanche-Olsen]

After much bisecting, much slowed downn and somewhat complicated by a
whole range of revisions that didn't even build, I have identified the
culprit: It's a one line addition (!) revision 109470 of trunk.

I have further verified this by patching the current tip of trunk
(revision 110013) as follows, which undoes revision 109470.

Without the patch, I see emacs freezing, using lots of CPU, and
sampling the process using Activity Monitor I get mark_object calls
nested "infinitely deep". Well, I don't know that, the saved sample
file is 74 MB big, and I just don't feel like analyzing it to bits.

My patch above is probably not TRT, but hopefully someone can figure
it out. Meanwhile, it's a workaround for Mac users.
