When I couldn't replicate your problem, I thought perhaps I was
running the mless function the wrong way, so I did this:

( zsh -fc 'print a few words; /bin/sleep 30' ) | mless -

This causes less to exit with a no-such-file error, at which point all
signals were ignored and no prompt returned until the "sleep 30"
finished.
