I am under the impression that the intention of LINUX_TCP_CORK is that
when you 'reset' (zeroize?) this particular socket option, the local
data queue is flushed into a TCP packet on the wire. Whereas unsetting
TCP_NOPUSH will not trigger a flush by itself. As I understand it NOPUSH
and TCP_CORK have subtle differences.

Kind regards,

Job
