But that's a completely different problem from the one
we're investigating. The problem is about how the terminal emulator
reacts to Emacs's output, not how Emacs reacts to the terminal
emulator's output.

We try pretty hard to avoid using such timeouts in Emacs, so by and
large this doesn't apply to Emacs at all.

But the present bug-report is about the other case.
To repeat the problem:
- a particular run of Emacs sends bytes <typescript> to the terminal
emulator, and the result doesn't look right.
- yet when we replay the same <typescript> directly to the terminal, the
result looks correct.
Note also that (other than the display), the state of Emacs at the end
of the test is correct (and forcing a redisplay indeed fixes the
display), so the problem is not in Emacs misinterpreting input because
of timing issues.
