In the future, it may be possible to use userfaultfd but not currently. This alternative patches tries to achieve the same effects that this bug requires. It is not perfect, e.g. there are some unfixable race conditions and performance overhead, but it shouldn't break anything unlike the previous attempt. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
