What do you mean here by "actual handler" and "underlying handler"?

Wouldn't it work to let-bind process-connection-type to nil around the
function that starts the async subprocess?

And I still don't understand why some people (like Lars) cannot
reproduce the problem at all -- the issue sounds like something that
should fail deterministically on any GNU/Linux system.  What am I
missing?
