The periodic UI hangs started happening a few months ago, and I
suspect are unrelated to the X crashes I was having earlier today.
They seem to be a fairly straightforward block in libzephyr trying
to cancel out the zephyr subscriptions, even though the reason it's
closing the connection is that it wasn't able to connect to the
zephyr server in the first place.
I imagine my earlier crash was some sort of memory corruption that
has since moved to someplace less damaging. I'll keep running with
the libzephyr version, put up with the hangs, and hope the crash
shows up again.
The stacktrace for the zephyr hangs:
