I can't speak for the core developers, but IMHO the chances of this
being included in 7.3 are basically zero.

Cheers,

It might be nice to point out this has more to do with beta being about
3 days away rather than any quality of code issues... (For the record
I'm not a core developer either, but I think this is a fair assumption)

Yes, zero chance for 7.3.  However, we have point-in-time recovery and a
Win32 port all almost ready for application, so if we can get those
three in, we can shoot for a 7.4 fairly quickly.

Boy, that's starting to sound like an 8.0 ;-)

Yes.  We are resisting a delay to get those all in, but I think a quick
release after 7.3 is very possible.

I note that, if you're right, the old six-months-and-release plan
would be back on track.  So we even get meta-level good news here :)

This is correct ... will have to wait for v7.4 ...
