Lots of little bits and pieces here. Most notably I've started to
look at the scheduling latency of the uniprocessor preemptible kernel.
It was actually pretty awful. Most everything in the MM/VFS area has
been fixed here, and it is now achieving 500 microseconds max latency
at 500MHz.
With the notable exception of the case where a task exits while holding
a large amount of mmapped memory. 300 milliseconds for a 700 megabyte
mapping, and a couple of milliseconds while just running cvs. This will
take quite some fixing.
Only ext2 has been done. Other filesystems will need attention.
