    BTW, I can't seem to find any reference to fcntl(2) in the manual.  Is
    this because it's not documented, or because it's not supported (e.g.,
    non-POSIX), or because I'm not looking hard enough?

    Useful things you haven't mentioned might be reading/setting file
    modes (asynch, blocking, append)

You can *already* do these things in scsh if you are willing to specify
them when you open the file. See OPEN-FILE in the scsh manual.
