@lambdageek any estimate on this one?

No estimate.

It's not particularly actionable: there's one thread that's in an unexpected state - the GUI thread.

The GUI thread suggests that this may be related to #11138 - xammac pulses a lock from an icall which leads to hangs in some circumstances. So it may be that this is the same issue.

If we get more reports about hangs while typing, there may be more to do here.
