Yeah.

Whatever happened to the Boehm GC branch?  That seems like the simplest

Here's a script I've been running on the GDB sources:

I've profiled (using oprofile) Emacs running this a few times; typical
results show mark_object at 10-12% of runtime.  It is probably pretty
easy to reproduce this with a variety of elisp programs.
