Most peculiar. It looks like omniNames (on Linux) is not trying to
send replies to the client. I don't know why that would happen. Try
attaching to omniNames with gdb while it is blocked, before the client
times out. By looking at the threads, it should be possible to see
where it's held up.

It's more likely just that gdb isn't working.

I don't know. I think it's most useful to track down what omniNames on
Linux is up to, since it seems to be doing something wrong, and we
know that it ought to work there. Once that is understood, it will
hopefully help with understanding any problems left on the
PlayStation.

Cheers,

Duncan.
