Well, note that the merge window is opening *soon*. I haven't yet
moved the master branch, so I can update the patch set, but I'm going
to need it soon.
Can you let me know what changes you need to make? If it is to add
new features or new sanity checks, does it make sense to simply make
it as new commits to existing patch set? Or are there fundamental
problems with the current set, that would be better to fix in the
current set of commits? (Or is it just minor stylistic/spelling
fixes?)
Thanks!!
