  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.
