It's not quite as simple as that.  This software has to run reliably
on millions of systems with thousands of combinations and permutations
of configurations.  It's doing that right now.  There've occasionally
been examples of a change made perhaps a little too hastily which gave
grief to many users and rise to a lot of spleen-venting on the users'
mailing list.  It would be a brave decision, in the face of the valid
concerns noted in #10979, to release a new version, world-wide, for
production use, which contains the patch that I'm running now merely
as an experiment with my eyes wide open on a server that crashed four
times this month because I'm also working on some netfilter stuff.

This is a community effort.  If you're familiar with C it isn't at all
difficult to apply the patch, and I'd be happy to mail the two patched
files (56kBytes in total) to anyone who didn't feel up to applying the
patches themselves.  Then, if you felt brave enough, it would _almost_
be as simple as

./configure && make && sudo make install

to build and install it.

Incidentally I'm a Sendmail dinosaur, and the default timeouts appear
to be longer for Sendmail than they are for Postfix.  I'm sure it's
easy to make them longer for Postfix; then this issue would, if not
disappear, at least more or less be transparent.  It really isn't that
big a deal if you know what you're doing.
