OK, the escape from purgatory: CTRL-Q negates CTRL-S
And it doesn't only happen in Vim. Try this:
$ cat > /tmp/fred
asfga <- type some characters, then CTRL-S, followed by more "gggggg"
<- No output. Hit CTRL-Q, then the characters come out:
asfgagggggg
So it happens even in the terminal. It's not a bug. CTRL-Q has
traditionally sent an XOFF, and CTRL-S an XON, where x stands for
transmit (xmit). These are used on serial links where hardware flow
control is lacking. So your CTRL-S served to turn off data flow.

Ah, recalling how a new user reacts to acute weirdness, like console
lockup, I wonder if that note's prominence is entirely user friendly?
