Looks like the issue is that there's an ordering requirement that the window lock should be "inside" biglock, but because TextSelect drops bigLock before reading from the mouse, xfideventread manages to acquire bigLock but then can't acquire the window lock because TextSelect still has it.
Seems like this is a potential problem anywhere we bigUnlock while holding some other lock.
I'll try getting Textselect to drop the window lock before calling bigUnlock, but it's quite possible that might
mess up some invariants.

I'm reverting 6faf3d8 in my copy for the time being because it's not easy to drop the window lock from inside Textselect.

Here's another one - it's not OK for xfidlog to drop the bigLock while the winlock is held.
