At most 6 fds for signalling to the user (pipe/socketpair/eventfd

But they should be counted on the user side?
And why 3 channels and not 1 for signaling any event?
I somehow mitigated this in the latest trunk:
1. NN_ERRFD option was removed. Instead both NN_SNDFD and NN_RCVFD are
signaled.
2. For unidirectional sockets (send-only or recv-only) the
NN_SNDFD/NN_RCVFD option doesn't exist.
Thus we can get as low as 3 fds/socket on Linux, or 4 fds/socket on
OSX.
