A couple of > times, it crashed saying memory was full. 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. Stefan
