non-blocking disk I/O

Ok one more question.  The docs for perlbal say it does non-blocking disk
I/O.  I didn't think most Unix OSes, including Linux, supported
non-blocking disk I/O.  Squid, for example, gets around this by using
either separate threads or processes to do disk I/O.  How does perlbal
solve this?
