I run this function for ~1.5 hours without stopping: (defun yyy (n k &optional tup) (if (< 0 k) (mapcar (lambda (x) (when (or (null tup) (> x (car (last tup)))) (yyy n (1- k) (append tup (list x))))) (number-sequence 1 n)) ;(message "%S" tup) <- yes, this was commented out )) ;; I started yyy this way: (progn (message "start: %s" (current-time-string)) (yyy 90 5) (message "end: %s" (current-time-string))) ((I know mapc should be used above instead of mapcar; but think this is a test program. It caused Emacs22 to give a "Warning! Memory limit exceeded" on Windows2000 with 4GB memory, after running for ~20 minutes... -- now I tried to reproduce this on Linux with Emacs23 with 1 GB memory. The warning didn't come, but the following happened: )) Emacs eat up all of the memory + a big chunk of the swap: Emacs itself used ~620MB memory after 1.5 hours (not really increasing after some time). Then I decided to stop it. Went to Emacs and typed C-g. Nothing happened for a while, but after that buffer content was redrawn and I could move the point (with the arroy keys): I thought yyy-process is stopped and I can use Emacs again. But after a while Emacs again stopped responding. Even the buffer content was not redrawn. I tried C-g again and again, but nothing happened. I hoped just memory freeing takes a long time, so left my PC for some minutes. This didn't helped either. But after a while I could again use Emacs: killed the buffer (containing yyy) and moved around the point just to see it works. But memory still was occupied: Emacs used ~600MB. Later I killed Emacs (with C-x C-c) and got back the memory. I think Emacs should free the memory if I stop the process (with C-g) what filled up the memory...at least after some minutes garbage collection should work? Or is this behaviour described above a feature of (keyboard-)quit?
