I am also possibly able to trigger the problem before I load
emacspeak;
After running emacs -q -- and then M-x shell, I see all of the
memory on the machine getting shewed up -- at least as reported
by free.
I'm attaching outupt of memory-usage from both instances so they
are in the same message; see what you think.
The memory usage numbers with M-x shell dont look as big as the
ones with just emacs -q -- but they do look bigger.
Plain: memory usage in emacs -q
