Interesting. I was about to suggest setting 'timeoutlen' to 100. But,
that's the opposite of what you're looking for. (It will wait up to 100
milliseconds for the next keystroke.)

I like the idea of 'mapwait', because it seems like the false-positive
rate could be very low (problems w/ spotty internet?), but the
true-positives that it would catch would be pretty numerous. Maybe set
it much lower, though, around 10ms. I'm an okay typist (60 WPM
according to an online test¹), but testing it via some Perl², my minimum
time between keystrokes was around the 50ms mark.

On the other hand, probably a less error-prone approach would be to
provide (or fix?) support for bracketed paste mode³. It's been
available in XTerm for a long time, and it's also supported by
rxvt-unicode. Unsure of its support in derivatives of either. And it
was disabled by default for a long time (might still be?).
