Alternate isolation backends

WebAssembly with wasm2c is just one way to isolate running code. We have focussed on this so far as this is the approach that is being used in production in Firefox today. However, RLBox's plugin model is completely general, and can be configured to support other isolation backends as well.

Note that the below plugins are experimental and are not actively maintained (which may mean they have compilation bugs that you'd have to fix). This is meant purely as a reference for you to write your own plugins.
