I just ran GAP (4r3, patch 5) on a Windows 2000 machine with 512MB of RAM
and a swap file size of 288MB with -m 383m passed to GAP. Anything larger
than 383MB seems to choke this machine. I have experimented with different

I do have a newer version of the cygwin1.dll than comes with GAP, and that
may explain why I am able to have a larger workspace for GAP than Roberto
even though I have less main memory.

Thank you: that's the point. I tried on another machine (Windows 98, 64
MB of RAM) and the limits are the same: 127 MB with the original
cygwin1.dll and 383 MB with the latest version.
