This is not caused by your patch, but in these two functions we return
without dropping the lock. There may be other places as well, but these
are the two I can see without leaving my email client.
Do you think you could fix that before we forget? Just change the
return to a break to fix the bug.
Sure, I'll address this issue in the next series
of patches. Thank you for bringing up this issue!
