Thanks.  This was exactly the kind of thing I wanted to hear when I
asked if ab/pcre-jit-fixes is a good base to further build on.

As far as I am concerned, ab/pcre-jit-fixes and anything pcre that
are still in flight are fair game for a reboot during this cycle (I
hope I did not merge any of them to 'next' by mistake yet).  If
there are bad apples queued on 'pu', let's make sure we eject them
and rethink the way to address the issue(s) they wanted to address.
