This bug report is against the feature/tramp-thread-safe branch,
162353c45c.

Continuous typing during an asynchronous find-file will result in
garbled input because the cursor periodically jumps backwards.

To reproduce, with emacs -Q, *scratch* as the current buffer,
and a remote machine with the Emacs source tree:

C-x & C-x C-f scp:server:src/emacs/lisp/emacs-lisp/b*.el RET

Then type "The rain in Spain falls mainly on the plain." or other
sentence of your choice, over and over.  Stop when the message about
checking vc-registered appears in the echo area.

Result: There will be a pause before the first typed text appears, then
Emacs will start showing the typed text normally, except periodically
the cursor will jump backwards so text will be inserted in the wrong
place.

After the first vc-registered message, Emacs will stop responding to
input until after a buffer for one of the opened files is displayed.

I'm running Emacs on a laptop which is using my cell phone's mobile
hotspot to connect to a machine on my home network, meaning there is
significant latency.
