Stay tuned, we are about to release a new version of Wasmer with WASIX, that allows for things that can't currently be done with Pyodide:

  * Multithreaded support
  * Calling subprocesses
  * Signals
  * Full networking support
  * Support for greenlets (say hi to SQLAlchemy!) :)

It requires a small effort in wasmer-js, but it already works fully on the server! :)
