When a Send is done over the network, does all the data get sent at once or
does it get sent as the receiver reads it?
/* Is all the data on this node at this point?/
pid = Receive( 0, &msg, sizeof( msg ) )
/ or is the data transfered here? */
Readmsg( pid, sizeof( msg ) - sizeof( char ), &some_data,
izeof( some_struct ) );
My gut tells me it all there when Receive unblocks…
