-## Why are all the tests async?
-
-The _technical_ reason is that some tests might have to be augmented to be asynchronous in the future. For example, Firefox is planning to [make a change][ff coop] that would require a `postMessage` call to detect SABs, which are required for threads.
-
-The _other_ reason is that you _should_ be using `WebAssembly.compile`, `WebAssembly.instantiate`, or their streaming versions `WebAssembly.compileStreaming` and `WebAssembly.instantiateStreaming`, which are all asynchronous. You should already be prepared for asynchronous code when using WebAssembly!
