rcvbuf option

[atarob]

The config listen option rcvbuf which maps to the TCP SO_RCVBUF, is applied
to the listening socket, and not inherited by the accept()ed connections. So
if you have a high load application where the legitimate request is bound to
be no more than 4K, for instance, you could save a lot of RAM by dropping
the default here  without changing it at the system level.

I straced nginx and it does not seem to actually apply the settings through
a subsequent setsockopt to the accepted socket. Is this intentional or an
oversight?

Thanks in advance.
