I did a new install of ubuntu and squeak and compared linux-rt with the
standard kernel. 

The delay bag test results were so poor on the -rt kernel that there's
no need to trouble with posting them from the test computer.  Half the
delays were 4ms.  The rest were basically worse.  Some up to 45ms.

The stock kernel was >98% at 1ms and the rest up to 16ms.
