As I recall, some posts to this list say that Windows provides non-blocking i/o for sockets but not for files.
No, Windows does provide non-blocking I/O for regular files, but it's a completely different mechanism than the one used by winsock. You'll have to use win32all and enter the Dark Side, that is Windows APIs.
You don't want to do that if you're not already familiar with CreateProcess, CreatePipe, overlapped structures, WaitForSingleObject & al...
