Not from me. Could just add something like this: "The most common
cause of this error is that your system does not have enough virtual
memory available to allocate the total simulated memory that you are
trying to create." Honstly though, for this instance, we should
probably have a wiki page for this error that goes into the various
issues (32-bit limitation, virtual memory (i.e. RAM+swap) limitation.
Maybe we should add back the web page thing for error messages, but
instead create a version of fatal (fatalw? fatalweb?) that sticks in
that automatic thing for us (or we could create error codes). By
having the separate version, we'd be explicit about having the URLs be
valid and not point to some non-exsting web page.
Finally, for this specific error, the perror("mmap") should possibly
be part of the fatal like this:
fatal("could not mmap (%s)!", strerror(errno));
Then maybe people would read it more closely. Alternatively, we can
check if errno == ENOMEM and print a special message for that.
