Does anyone see a better way?


I do not have a better way, but maybe a suggestion.
First, my experience with Fedora 19 is:
octave:3> system('sleep 30')
^Cans =  2

Hangs until time count down:
octave:1> sleep(20)
^C^CPress Control-C again to abort.

octave:1> system(sleep(30))
^C^CPress Control-C again to abort.

For sleep() would it be useful to implement code that does the sleep
to do the actual sleep which is not interruptable  in
short increments, checking  for interrupt at end of each increment?

Likely, you have a general solution that will work, which would
obviously be better.
