Not sure, a couple of seconds. I'm on an SSD, so that should be enough
to save any state. Quitting aptitude normally (from the "full" window)
does not occur any noticeable delay.

Hm, I hit "Enter" a bunch of times and also pressed some random letters.
Nothing. Then I did Ctrl-C, and then I got a prompt (and some old
prompts, from the "Enter") -- and the random letters were somehow
transformed into garbage bytes most displayed with that "?"-like symbol.

I just tried this again -- and indeed, after ~1 second, the black goes
away and the normal terminal appears. That was after just installing one
package, maybe it takes longer when many packages were affected? I sure
felt like I waited at least 3 seconds before doing Ctrl-C.
  In any case, it would be helpful if aptitude could display something
about being busy, instead of going all black.

Oh, I see... well, that's how I quit aptitude for months already, and so
far it kept working. ;-) But I'm actually very happy that there's now a
more "official" and reliable way of doing this :-)

Kind regards,
