Proposal:
The zstandard wrappers should be thread-safe and should not allow any multithreaded use (particularly under the free-threaded build) that is not considered safe by the zstandard C library.
Another thing to look at is using TSAN to verify thread safety in the C extension. I don't know offhand about if you have to do anything special to use TSAN with new tests in the CPython test suite.
Has this already been discussed elsewhere?
