I would like to note that this does have a significant drawback.

If you have to update the GUI every time something happens, it has a
tendency to lag in a big way.

You can alleviate this by only updating every X updates, however, this
adds a problem of constantly checking whether or not the update
threshold has been reached.  It's far simpler to use the mutex
approach, even though it is slightly more difficult to implement and
harder to understand (if you're not familiar with it).

Once I tried having the working thread update the GUI in Java....
locked up the whole GUI during operation, so if you wanted to kill it
you'd have to kill the running JVM - not fun!
