thanks for this.  i'd been working on the same myself.

do you have a reliable way to trigger this issue?  i thought that
returning to userland with a lock held would do it, but i wasn't
able to get that to work reliably.  there's more work related to
crash dumps i'd like to work on but i got distracted by testing a
change similar to this one and didn't get back to it yet.
