While reviewing the flaky list of branch-3, I found a very critical problem which may cause a procedure to hang forever.
I set it as a blocker for all upcoming releases, but to be honest I still need some time to see how to actually fix it, and may also need some proper tests. So if we want to cut 2.6.3 and 2.5.12 soon, I'm OK to reduce the priority and move 2.6.3 and 2.5.12 out from the fix versions, since the bug has been there for quite a while... Thoughts? Thanks.
