783,CMapGeneratorWorker isn't thread-safe,Philip,historic_bruno,"`CMapGeneratorWorker` runs in a non-main thread but calls `fs_util::GetPathnames` and `ScriptInterface::LoadGlobalScriptFile` which aren't thread-safe. (Those are the only problematic ones I see currently.)

This results in assertion failures in debug mode for me, and it could crash if e.g. hotloading occurs while the generator thread is running that function. (I've added some extra assertions now to make it complain more immediately.)

Either VFS needs to be made thread-safe (which sounds very hard), or the generator needs to avoid calling those functions except on the main thread. Maybe `Initialize()` can read the script file into a string, and enumerate all `maps/random/*/*.js` and read those into strings too (there won't be loads so it should be fast enough), and then the generator thread passes any requested files into `ScriptInterface` as strings so it doesn't need to interact with the VFS again.",defect,closed,Must Have,Alpha 5,Core engine,fixed,,jan
