+// rayon::ThreadPoolBuilder (used below) executes spawn handler to populate the worker pool,

+//
+// Normally, we could use postMessage directly inside the spawn handler to
+// post module + memory + threadPtr to each worker, and the block the current thread.

+// never be able to unblock us.
+//
+// To work around this problem, we:
+// 1) Expose `worker_initializer` that returns module + memory pair (without threadPtr)
+//    that workers can be initialised with to become native threads.
+//    JavaScript can postMessage this pair in advance, and asynchronously wait for workers
+//    to acknowledge the receipt.
+// 2) Create a global communication channel on the Rust side using crossbeam.
+//    It will be used to send threadPtr to the pre-initialised workers
+//    instead of postMessage.
+// 3) Provide a separate `start_main_thread` that expects all workers to be ready,
+//    and just uses the provided channel to send `threadPtr`s using the
+//    shared memory and blocks the current thread until they're all grabbed.
+// 4) Provide a `worker_initializer` that is expected to be invoked from various workers,
