three options

1. change it as you state based on it slipping

2. 2009.5.0-rc4 goes to 2009.5.0-rc5 in January and we just accept a minor 
'oops' on the version number

3. 2009.5.0-rc4 goes to 2009.5.0-rc5 in January becouse we base the number 
on when the merge window opened, not when it's released.

personally I think 3 is the clearest to explain to people, but I don't 
like 1 (it's not that bad, but it leaves a lot of mail in archives and bug 
reports listing the 2009.5.0 version number when no such version was ever 
released)

absolutly, the stable version is the Nth revision of the kernel that was 
released in December, it doesn't matter when the stable release happened 
(similar to the 2.6.16.X kernels that have been released)

they are marked in the release announcemnts, and code that cares can do 
'is version > 2009.5' logic.

this sort of test is done today by software so that they can enable better 
functionality on newer kernels, the size of the difference shouldn't 
matter.
