GIL

https://jython.readthedocs.io/en/latest/chapter19/#no-global-interpreter-lock No Global Interpreter Lock

Jython lacks the global interpreter lock (GIL), which is an implementation detail of CPython. For CPython, the GIL means that only one thread at a time can run Python code.

Again, Jython does not have the straightjacket of the GIL. This is because all Python threads are mapped to Java threads and use standard Java garbage collection support (the main reason for the GIL in CPython is because of the reference counting GC system). The important ramification here is that you can use threads for compute-intensive tasks that are written in Python.
