Indeed.  And not one I've heard before.

IOW, the problem is not that the GC is taking longer but that the memory
is filling up with many Lisp objects.  You can try M-x profiler-start
RET mem RET ... use Emacs for a while ... M-x profiler-report.
Tho this will only shows us where memory is allocated, which will
contain lots of places where that memory is later correctly reclaimed.
You can also try the install memory-usage (from GNU ELPA) and then M-x
memory-usage RET.  Again, it won't give us very much info, but might
still be helpful.
