If I start gnus using movemail to read my mail my xemacs image size grows from about 8Mb to 20-30Mb (this is with a fixed cygwin from Chris Faylor). If I quit gnus the memory usage does not go down at all. Is this what people would expect? What does it look like on a UNIX machine? I'm just wondering whether GC is actually collecting anything and how I prove whether it is. andy --------------------------------------------------------------------------- " .sigs are like your face - rarely seen by you and uglier than you think" Dr Andy Piper, Technical Architect, Parallax Solutions Ltd mail: andyp(a)parallax.co.uk web: www.parallax.co.uk/~andyp
