While I like the idea of this patch and how you implemented it, I
wonder if it's appropriate for code freeze.
The main problem in that bug is that the CA driver can deadlock, or
release memory out of order. When working on this patch, were you able
to identify specifically where the contention is? The idea of the
InTransition state was to handle the lock release in mid-call. Can we
add a check for that state in the callbacks to solve this problem less
The first patch seems fine.
