+ WebAssembly threads: initial implementation of the WASI threads proposal:
...
https://github.com/WebAssembly/wasi-threads
Note that the WASI folk have already declared this proposal 'obsolete' and
only intended to be used for engines that support WASI v0.1. On the other
hand, the WASI v0.2 threads proposal is an early draft and not implemented
anywhere, so we have no choice, but to stay with v0.1 at this time, or give up
on multithreading for who knows how long it would take for the v0.2 spec to be
completed.
Regarding the WASI v0.1 engines that implement WASI threads correctly and can
be used with Free Pascal, I've discovered only one that works:
https://github.com/bytecodealliance/wasm-micro-runtime/tree/main
Wasmtime claims to support multithreading since version 15, however it doesn't
seem to work. I tested all versions until the 23.0.1, and none of them works.
Caveat: using the internal linker is not yet supported with WebAssembly and
multithreading. Please use the external linker (the -Xe option), if you want
to give this new feature a try.

* WebAssembly threads: fixed race condition LockMutex in the check where Locked
...
is 1, but Owner still holds the current thread id, even though another thread
has just acquired a lock, but still haven't updated the owner thread ID. We
avoid this problem by setting Owner to nil before unlocking the mutex. And in
InitMutex/DoneMutex, we store the creator thread ID in a different field -
Creator, instead of Owner.
