        posix_mq 0.2.0
        
        This release fixes notification (un)registration and should be
        fully-supported on modern FreeBSD (7.2+) releases.
        
        POSIX_MQ#notify=nil correctly unregister notification requests.
        POSIX_MQ#notify=false now provids the no-op SIGEV_NONE
        functionality.  Under FreeBSD, using IO.select on POSIX_MQ
        objects is now possible as it has always been under Linux.

        support POSIX_MQ#to_io under FreeBSD
        
        FreeBSD implements an __mq_oshandle(mqd_t mqd) function
        to convert mqd_t to integer file descriptors.

        fix build under FreeBSD 7.2
        
        FreeBSD seems to need some files explicitly included.

        Fix mq.notify = nil to unregister notifications
        
        "mq.notify = false" also works now, doing what
        "mq.notify = nil" used to do (using SIGEV_NONE).
        
        I was confused by SIGEV_NONE usage vs using a NULL pointer for
        the notification passed mq_notify(3).  SIGEV_NONE does not
        actually unregister, it registers a no-op notification which
        prevents other processes from taking us.
        
        This also fixes the test case to pass under both Linux and
        FreeBSD.
