> On *ix, threads don't use up file descriptors

Thanks - this caused me to dig into the specific scenario where creating threads was exhausting file handles in my experience and you are correct - consuming a file handle is indeed not intrinsic to creating a new thread in Linux. It's insanely easy for literally anything you do with the thread to consume a file handle, but of course, that applies to virtual threads as well. Thanks!
