[Newbies] Block other processes?

Yes, that makes a difference!

In general, a Morph's step method runs to completion.  However, if you
had a higher-priority process running in the background, it would be
possible for it to be interrupted.  That probably won't happen unless
you write the background process.  If you do, you'll have to worry
about the fact that most Smalltalk classes are not thread safe.
