Hi,

I am observing a rather weird interaction between tramp and comint. Saving and
editing files on remotes is pretty snappy till I open a shell buffer. Once a
shell is open it can take good 10s to save a buffer. Editing and navigation are
also impaired.

Steps to reproduce:

  1) emacs -Q
  2) /ssh:remote-host:tmp.txt
  3) save tmp.txt (snappy)
  4) M-x shell
  5) back to tmp.txt and save (terribly slow)

Can anyone reproduce this?

This is a 6-month old development version, so the first thing to ask is:
can you yourself reproduce this with the current emacs-26 branch?

Damn. I actually pulled and recompiled before sending ... but it wasn't on
master :-/

It's fixed in master. Thanks!
