instead of our native library. I've left the native library support in in case the Sun stuff is not available, but that's so extremely unlikely in a server environment (IBM recreates Sun's signal handling in their VM because it's so dang useful) that I should probably just nix it altogether and simplify things. git-svn-id: svn+ssh://src.earth.threerings.net/narya/trunk@4710 542714f4-19e9-0310-aa3c-eee0fc999fb1
