I can't believe that it's intrinsic to 2.6 . We're using an up-to-date
Debian 4 release, and getting response times in very small fractions of a
second using msgsnd/msgrcv. It's a music playing app, and even a delay
like 1/4 second would be intolerable. We've paid no great attention to
setting up the message queue -- just used nice to give priority to our
critical processes.
