GC_CHECK_MARKED_OBJECTS is broken with threads: PVEC_THREAD objects are
not found via mem_find (but they should be?) and GC_CHECK_MARKED_OBJECTS
assumes that any such vectorlike object must be a subr.  I think it's
been broken since the threading branch landed.  Maybe we should enable
GC_CHECK_MARKED_OBJECTS by defaults when --enable-checking.

Could you please file a bug report with all the details of the
failures you saw?

Could be.  Does that incur any significant slow-down?

IIRC the overhead is quite reasonable (much smaller than that incurred
currently by --enable-checking).

I think I fixed this in master, please test.
