Folks, I'm not interested in rehashing this. I don't know what all the
open file descriptors are. Some/many/most will have been opened by
underlying C++ libraries and will not have been opened by code at the
Python level. I do think the addition of an os.fsync() attempt on each
file descriptor before calling os.close() makes some sense to me.
Beyond that, I'm not sure there's more that can be done.

I sent my last message simply because I was surprised os.closerange()
existed. I have no idea why it didn't turn up in my original
searching.
