Also 32-bit machine here.

"opening and closing" means loading some source file (C, Erlang,
Text, Haskell, M4, something else) and maybe erc-tls. Then after nuking
all buffers and emacs using minimum 100 megs I wondered why no
gc kicked in to reduce it by at least 30 megs (random number).

Are there known leaks with erlang-mode or haskell-mode?
Can there be leaks in major modes or other addons like
ido extensions or custom themes?

Darwin 64bit and Linux 32bit

I believe I tried that to no effect. Will retry and take notes.
