Tested with download binary for zig version nominated by Mach.

Run app (using sysgpu) and immediately close it.
Expected result is diagnostic output withour errors.

I don’t know if this is significant. But when I use a local build of zig master, "zig cc -v" shows a more specific target.

➜  zig git:(master) zig cc -v

Thanks for the issue! Hopefully soon I can track down why the queue isn't freeing.
