Hi Alan,

This may be slightly off topic, but we have provided an LGPL module for
RTAI (linux real time extensions) that implement POSIX queues (for
RTAI).  We are hoping that we will be able to provide some level of
EL/IX compliance for realtime under Linux by adding to this set of
modules.  It may be possible to make use of this code from Linux ?? I
think the latest RTAI release comes with this modules (look at
http://www.rtai.org/ )
