What to do when you have less than 1000 file descriptors?

Hi all, at first, sorry for the long topic name.. could not think of anything shorter. I had a problem with Tor on my NetBSD (4.0.1) box, it said: Mar 15 17:51:09.357 [warn] We need 1000 file descriptors available, and we're limited to 956. Please change your ulimit -n. Mar 15 17:51:09.359 [warn]

When will be "ExitNodes {...}" feature be released ?

As far as I know the ExitNodes {..} feature for determining the countrys exit nationality is currently in alpha stage. When will it be stable and released (approx)? Is it a matter of days/weeks/month/years? Thank you Ben
