[question] How to await all run dependencies (data-files) to be satisfied?

I'm using emscripten in a Worker. I'm loading data packages manually (by doing `importScripts` on the data package JS files with unfortunate necessary hacks around static variables https://github.com/emscripten-core/emscripten/issues/12347), and then calling main manually, so I'd like to await until all the data-files are loaded / run dependencies met.

Is there a way to achieve that?

Currently I have two processes independently: the program executes (and fails, because required files are not present in FS) and also complains that it still waits for dependencies to be satisfied.

Thanks!
