I seem to recall a bug ages ago in which you could fault twice on an address
and end up with two references even though there was only one atl. This was
fixed in 4/19/94.

Another possibility is that your fault handling code is not getting read,
write, and copy-on-write exactly right. Not as likely for ZFOD areas like
the stack.
