I'd like to do that, but it it not easy to detect this condition. POSIX
does not specify an error code for it, Linux uses EPERM (which can also
occur under different circumstances), FreeBSD uses EOPNOTSUPP, and
Windows uses ERROR_INVALID_FUNCTION which I translated to EPERM to be
compatible with Linux.
