Could both of you please record the terminal commands issued while you
reproduce the problem in a termscript, and then replay that termscript
to the same terminal (outside Emacs) with the attached shell script?
I'm interested to see whether the problem is reproduced by sending the
same commands at a low rate.

If sleeping for 2 seconds doesn't reproduce the problem, maybe try
decreasing the sleep time until it does.

TIA
