This does seem like a bug...  if Emacs is using a mark-and-sweep garbage
collector, which I thought it did.  But Andreas (in a different bug
report) seemed to imply that Emacs uses a conservative garbage collector
these days, and I see that there's some talk about that in the source
code, but...  it's documented to be a mark-and-sweep gc.

So now I'm confused: Is Emacs still using a pure mark-and-sweep gc as
the Emacs Internals section of the elisp manual says?
