There's no leisure in our pretests.  We need to wait until the bug
reports come in after each pretest tarball, that's all.  It takes time
for the reports to come in because Emacs is a very large package that
supports many different use patterns.

We never released unstable Emacs, and I'm not sure we should start.

IMO, there's nothing in this bug that allows us to assume it is rare.
