ggated not working on 6.2-PRERELEASE

I have CC'ed pjd too as this concerns ggate and I saw another thread
that looked like the same problem.

I am experiencing this too.

I will try to reproduce that here.

As far as I can tell, src/sbin/ggate/ggated/ggated.c line 634 calls 
g_gate_recv, which in turn calls recv(2) on src/sbin/ggate/shared/ggate.c
line 254.

recv is called with the MSG_WAITALL flag and receives an EAGAIN error.
Is that supposed to happen? If it is, ggated should probably handle it.
