I assume you mean :0.0? If not, that may be some Sun specific thing.
Anyway, if you set DISPLAY to :0.0 you let the Xlib choose "optimal"
communication mechanism to the X server, whatever that may be.
If you use hostname:0 you usually get TCP/IP over the loopback i/f (i.e.
stream sockets). Setting DISPLAY to unix:0 gives you unix domain sockets,
which usually is a bit faster than TCP/IP (but not much,
just a few percent on my box).
It is possible that :0.0 on your machine selects some means of communication
that does not work with SIGIO. Could be shared memory perhaps. Some
types of X over shared memory requires application support. Emacs does
not have that.
