I have one question about this whole issue:

Suppose I'm running a Multifinder-aware terminal emulator, I start a
download, and then switch into another application.  I know that the
download works fine so long as the application calls WaitNextEvent
frequently.  At some point the application puts up a modal dialogue,
which, as we know, prohibits switching.  Question: does it also
prevent the background download from running?

If the download is prevented, too, then I believe this is what someone
was talking about when they said that Apple has inextricably connected
input focus with computation.
