* Blocking I/O is enabled on any TCP type socket by default.
* For the UDP model if this is turned on then the socket buffer is
* shared for send resources amongst all associations. The default
* for the UDP model is that is SS_NBIO is set. Which means all associations
* have a separate send limit BUT they will NOT ever BLOCK instead
* you will get an error back EAGAIN if you try to send too much. If
* you want the blocking symantics you set this option at the cost
* of sharing one socket send buffer size amongst all associations.
* Peeled off sockets turn this option off and block... but since both TCP and
* peeled off sockets have only one assoc per socket this is fine.
* It probably does NOT make sense to set this on SS_NBIO on a TCP model OR
* peeled off UDP model, but we do allow you to do so. You just use
* the normal syscall to toggle SS_NBIO the way you want.
