Hi there, I just recently found out about this project - amazing work. I haven't dug in it yet as I'm glacing the documentation a bit, but I have a question.

The documentation states that codon supports multithreading out of the box via OMP; it also states that it provides interoperability with CPython by building codon code as a Python C extension. Given this, what's the effect on the GIL on a Python extension compiled via codon? For example in a producer-consumer pattern, where pure Python is the producer and a codon thread is the consumer and data is shared via a - say - FIFO, is this scenario possible in the sense that the GIL releases the data transmitted from Python to codon allowing to have a true concurrent thread? What would be the best choice for the FIFO? Should it be a codon FIFO which is exposed in the Python code?
