free threaded build

[astrelsky]

As far as I can tell, jpype is already thread safe as it was necessary since Java is a normal programming that isn't scared of more than one thread.

Anyone looking to use the experimental free threaded build of python should be anticipating to encounter some, uh, problems anyway. problem example

@marscher I'm a complete dinosaur when it comes to ci/cd stuff so I didn't touch any of it. In order to build the free threaded version on windows I needed to do python3.13t -m pip install -e ., so I'm assuming it's a similar situation with the other operating systems.

Thanks for this interesting contribution. Is the thread-free branch enabled by default when using Python 3.13 or how is toggled?

It is disabled by default. You must explicitly run it via python3.13t. It is available as an option in the windows and mac python installers. I don't see any information about Linux on the documentation page at https://docs.python.org/3/howto/free-threading-python.html I assume it would depend on the Linux variant and it's package manager for the free threaded build without having to build it yourself.

It took me about 8 edits to get that link right. It didn't occur to me that my phone stuck in the space in howto automatically
