Hi Bob, I’m working on coming up with a better solution.

Can you try the attached patch? So far the only problem I’ve seen is
that emacsclient doesn’t return to the shell when it exits. I suspect
it’s because I’m not monitoring write or exeption fds correctly.

If you spot any other problems, either reply here or to bug 25265.

Additionally, if anyone has any better ideas of how to deal with
ns_select, please feel free to let me know.
