Fair question. The Sep 15 submission happened too quickly for us to
mobilise testers, so the final submission was submitted with only manual
testing by me. Many last minute major bug fixes meant that the code was
much less tested than I would have hoped - you found some of those while
I lay exhausted from the efforts to hit a superimposed and unrealistic
deadline. I expected us to kick in to fix those but it never happened
and that was why I was keen to withdraw the patch about a week later.

You've been kicking hell out of it for a while now, rightly so, so I've
left it a while before commencing another set of changes and more
testing to follow.

It takes time, and money, to mobilise qualified testers, so that should
begin again shortly.

I agreed with you at PGday that we shouldn't expect a quick commit.
There are good reasons for that, but still no panic in my mind about
skipping this release.
