As was pointed out earlier, it requires POSIX realtime signal support to become useful in this way. I have programmed in this way under Solaris, for what it's worth; I implemented an httpd server using aio calls and real-time signals a few years ago, and the performance as compared to a select()/poll() based server turned out to be far worse, at least in terms of the number of requests per second it was able to handle. I don't recall specific figures. So I would regard it as largely a red herring; the kqueue/kevent mechanism will yield somewhat finer granularity in terms of polling for an i/o completion event from userland on FreeBSD, which seems to be what you're trying to achieve. aio and realtime signals is something we don't really do at the moment.
