FWIW, this SO_LINGER option predates Linux. It was already covered in
Stevens' UNP series, which didn't cover Linux (IIRC).

IMO, we don't need RFC 1122 (or whatever) to allow us to abort (i.e.,
ABORT()) connections (despite the reason). The ABORT procedure was
already defined in RFC 793, and there were no contraints at all wrt
*when* a TCP user is allowed to call it.

Thanks,
