That makes no difference.

I think `window--adjust-process-windows' finishes without error.  My
impression is that it's something that it does that causes the hang
later.  When I use debug-on-quit, window--adjust-process-windows is not
in the Lisp backtrace.

When I trace 'window--adjust-process-windows', I don't see unnaturally
many calls of that function, so it also doesn't seem to be part of some
kind of infloop.

Michael.
