There's an ongoing discussion/debate between two very knowledgeable and talented developers (plus a supporting cast) regarding the real-time support in FreeBSD; it's happening on freebsd-arch@: http://lists.freebsd.org/pipermail/freebsd-arch/2010-December/010835.html I suggest giving it a read if you are planning on deploying some real-time process (or are interested in reading about FreeBSD internals from some very knowledgeable people). -Brandon
