Hrm... tcp(4) is a bit ambiguous about this:
The TCP protocol implements a number of variables in the
branch of the sysctl(3) MIB.
TCPCTL_SENDSPACE (sendspace) Maximum TCP send window.
TCPCTL_RECVSPACE (recvspace) Maximum TCP receive window.
I don't know if setsockopt(2) will allow you to exceed these values. I
don't see anything in setsockopt(2) that suggests that you can't exceed
TCPCTL_SENDSPACE with setsockopt(2).

This is a wise course of action given the uncertainty of setsockopt(2)
and the net.inet.tcp.* interaction. I'd grep through the source and
give you a definitive answer but am busy/too lazy at the moment. :)
