Widgets can't pause code, and the kernel won't process widget updates while
the kernel is running in the main thread. You could probably hack something
together using generators and/or threads to make it look like it was doing
that, but I wouldn't recommend it.

Can you describe at a higher level what you're trying to do - we might be
able to suggest other ways to achieve it.
