Yeah, same here.
After some discussion, the core committee has concluded that we should go
ahead with the already-wrapped releases. 9.2.6 and below are good anyway,
and despite this issue 9.3.2 is an improvement over 9.3.1. We'll plan to
do a 9.3.3 as soon as the multixact situation can be straightened out;
but let's learn from experience and not try to fix it in a panic.
