Wow, thanks a lot!

I cannot review the patch, as I don't really understand the details.
So I suggest to push this and see if users report bugs.

(I presume you have run all the tests, including those in
test/src/thread-tests.el and those posted in the few recent
discussions related to thread-related problems.  If not, I very much
recommend that you do that, to see if the new code passes these
"entry-level" tests.)
