  21. I thought I heard a collective "Hmmm..." when this was posted :-)

  23. I've been tinkering with Security Enhanced VMS (SEVMS) which follows a
  24. write-up-read-down scheme. The bummer of it all is that VMS needs to do a
  25. read to see if the file exists before it'll write a new file. Yes, you can
  26. write custom procedures to get around this, but it would be nice if the $QIO
  27. routines were already "trusted" to handle this for the unpriv'ed user.
  28.  
  29. Overall, I've been happy with the $QIO service.  I'm interested to hear what
  30. your ideas are.  How about "broadcasting" the $QIO to a set of CPU's and the
  31. first CPU to complete the task "wins".
