I don't believe this to be true. Fibers are not preempted. The GIL is
released at regular intervals to allow the effect of preempted
switching. Many other behaviours of Python threads are still native
thread like, particularly in their interaction with other components
and the OS.

GIL + Threads = Simplified, non parallel interpreter
