It isn't that short, and we know not everyone will get time to test
the RCs. Frankly I have seen plenty of releases with extended RC
cycles, only to discover a critical issue days after release and make
a prompt bug fix release. Why make more than one RC if there are no
critical flaws discovered? It looks like ITK might have rolled a final
in 8 days had they not had to make a second RC.

If you have feedback we would welcome it, Monday is still a ways off
and it sounds like you will have the RC with QA tomorrow. We do a lot
of QA continuously, and test with various projects based upon VTK too.
