Sleep command

[Bastiaan Olij]

Hi Doug,

That still entails finishing whatever i'm doing and leaving the
interface sitting there waiting for the callback.
In many cases that is just what I want but in this particular case I'm
both dealing with some legacy code that will be hard to rewrite and the
added bonus of just sleeping the code is that I can make sure the user
can't interact with anything else :)

Cheers,

Bas
