The plan is that I am finished with the clustered/partition scheduling in May, 
this is when the GSoC coding starts.

The fine grained locking exists currently only as a rough sketch.

We have to re-structure large parts of the critical sections.  My hope is that 
once it is implemented for events and semaphores it will be relatively easy to 
do it for the other objects.  You need a good understanding of the inner 
workings of the RTEMS kernel.
