The deadlocks that were in 0.23 that were thought to have been worked
out of 0.24 are still there, or there are new ones. My 0.24 backend
locked up 3 times last night, apparently after, or perhaps during
recording. Here's a threaded stacktrace of my backend currently as it's
locked up:

My apologies for not having the debug symbols available. I will upgrade
my 0.24-fixes today and be sure to install the debug symbols.
When this deadlock occurs the log typically looks like:
