	No they aren't.  You cannot do certain things with your own packet
handling, even if you provide your own message ports.  Specifically, you
cannot implement both Reading AND Writing the handle at the same time
because this crashes most current day device drivers.  Also, my functions
include low (read) and high (write) water marks which are impossible to
duplicate your way:

	Another reason:  Sure, you can make your own packets pending, but
there is NO WAY TO ABORT THEM!  You *HAVE* to wait for something to happen!!!
YOU CANNOT CLOSE A FILE HANDLE WHILE OTHER PACKETS ARE PENDING ON IT!!!

	OK Pete, that last one is a very big item ... admit your defeat in
this particular bout!  "A time will come again for thee to take up thy
vocal prose".
