Comment (by vbraun):
By "absolute" limit I mean a fixed size (as opposed to relative to
available resources). 640kb (or any other fixed amount) is not going to be
good enough in the future.
The current GAP in Sage does soak up all the available swap and I don't
see anybody complaining about it. It does make my desktop slow down to a
crawl whenever the patchbot hits GAP, though. Maybe this patch is not the
ideal solution, but its a vast improvement over what we currently have.
As for the rest, read the mmap manpage. You either reserve swap or you get
SIGSEGV when you run out of memory. And GAP is not written in a way what
would handle that signal.
