But what if the same integer happens to be both a socket and a file
descriptor...? Overlap (i.e. smallish socket numbers) can very well
happen. I once had a test program to check this but can't find it
right now, but IIRC you didn't even have to try very hard to get
overlap (no need to open a stupendous amount of files or sockets).

Having the file/socket separation spelled out in the API is
unfortunately the only reliable way to handle this.
