PEPs 843, 844, and 805 push the free-threaded redesign into re-export syntax, public/private builtins, and runtime object-state checks, with Guido in the threads and ecosystem compatibility still unsettled.

On kernels without an MMU, pin and unpin refcounts were asymmetric, so repeated io_uring fixed-buffer registration could free pages still mapped by userspace.
