1 - Improved Bridge Performances (crn 393)
------------------------------------------

The thruput of the bridge subsystem has been improved a large factor. Following
is an example of the performance improvement coming with this patch.

Test results comparing 10(1) and 10(2) using a 20 items bridge (procedure
bridge_set_up.prc, simulator at 8 packets per second, 128 items decomposed per
packet, 124 items changing per packet, 160 items bridged per second) showing
the measured %cpu.

2 - New Task Scheduling Algorithm (crn 390.b)
---------------------------------------------

In previous releases, the task scheduling algorithm used in OASIS-CC was a
simple preemptive scheduling algorithm. With this patch OASIS-CC uses a 
priority inheritance scheduling algorithm. This algorithm bounds the duration
of priority inversion states when they occur.

3 - Increase Max Command Message Size (crn 398)
-----------------------------------------------

The maximun command message size has been increased to 524228 bits (from 
65000 bits).
