Emscripten: Get test suite passing #127146
Description
First I'd like to get the test suite to run all the way through, then to pass.
Update 2025/01/30
Emscripten 4.0.2 has fixes for all of the file system bugs I've looked into. There are still problems with nonblocking I/O which I haven't looked into.
