I haven't seen mention of this, but interrupts during disk I/O
can corrupt your disk.  ProDOS supports interrupts but they're
inhibited during critical timing loops.  If you need interrupts
but not disk I/O, nor other timing-critical peripheral-card I/O,
then you can certainly plant your own interrupt handler and
avoid ProDOS's altogether.

I have to agree that the Apple ][ family is really not designed
for real-time, multitasking use.  There's no reason it shouldn't
have been, except they didn't think of it in the first place.
