Is packet sending threadsafe?

Can I use the objects in the devices module from two threads simultaneously

[mitchgu]

With my understanding of how the GIL and python threads work, I think two threads on the same process actually can't run in parallel. Since the properties in the devices are assigned to more or less atomically, I think it's fine in most cases. Furthermore, the information flow is pretty one directional, as long as the user knows to never write to a device's property. I could be misunderstanding things though. If problems arise in the future I can add a lock to devices to access its properties.
