    Open the DAHDI pseudo device and set it to be nonblocking atomically
    
    Apparently on FreeBSD, attempting to set the O_NONBLOCKING flag separately
    from opening the file was causing an "inappropriate ioctl for device" error.
    While I cannot fathom why this would be happening, I certainly am not opposed
    to making the code a bit more compact/efficient if it also fixes a bug.
