From [here](http://docs.oracle.com/javase/7/docs/technotes/guides/security/PolicyFiles.html):

Let's use a simple 2-layer view (GUI, application logic).
The application logic work should be done in a separate Python thread. For Asynchronous events that need to propagate up to the GUI layer, use wx's event system to post custom events. Posting wx events is thread safe so you could conceivably do it fro... | I use threads so the GUI's main event loop never blocks. |

] | Definitely threads. Why? The future is multi-core. Almost any new CPU has more than one core or if it has just one, it might support hyperthreading and thus pretending it has more than one. To effectively make use of multi-core CPUs (and Intel is planing to go up to 32 cores in the not so far future), you need multiple... | For some types of operations, using separate processes makes a lot of sense. Back in the day, spawning a process incurred a lot of overhead. With modern hardware this overhead is hardly even a blip on the screen.
