Stepan, I am happy for you to do these things, but I do not want to wait for 
these before checking in some patches.

I will probably leave that to you.

I intend to process some of these Red Hat and other miscellaneous patches.

Number 8 sounds like a trivial, independent change.

Maybe, but ...

I believe we should see which of these we can fix quickly, and try to fix as 
many of these as possible before a release.  Any that are very difficult can 
wait until 2.5.3.  Some of these have good fixes, or at least good partial 
fixes, in the Red Hat patch set.
