One of the things I've noticed from previous releases is that few  
people actually pull the release and give it a go.  Or, when the  
first problem is noted everyone stops only to find the next problem  
after several days of voting.  We all need to complete as much  
testing as possible up front otherwise the voting takes forever.   
1.1.1 for instance was done by around August 10th and didn't ship  
until September 18th.  The code development was faster than the  
release process.  Part of that was latent issues that should have  
been identified years ago (like missing LICENSES / NOTICES, etc.).   
Hopefully most of that is behind us now :)

Since TCK generally takes a few days to run it might make sense to  
include more than one OS.  So we could do a Windows, Linux, Solaris  
x86 in a rotating cycle.  This would get results every day and we'd  
also make sure we weren't running into wierd OS issues that pop up  

This also means that we need all committers to sign the NDA for the  
TCK so they have access to the results.  At least it would be nice to  
have everyone disclosed.
