I'm surprised it does anything at all actually, isn't the (add-to-list
'buffers ...) call a bug? Should be using `push' I think.

-              (add-to-list 'buffers (generate-new-buffer "foo")))
+              (push (generate-new-buffer "foo") buffers))

I noticed you added a with-timeout on that test, but it doesn't seem
to be working. Maybe a stronger method would be to use

    (start-process "*watchdog*" nil shell-file-name shell-command-switch
                   (format "sleep 350 ; kill -SIGUSR2 %d" (emacs-pid)))

By the way, I hit the "`tramp-test36-asynchronous-requests' timed out"
message when running locally in an -O0 build, although it succeeds
with an -O2 build. Maybe I just have a weak CPU.
