This is caused by the way the providers are unregistered is handled in 
"make preuninstall".

The RASDs are defined in on mof / registration file.  So when the RASD 
classes are registered, <>_ResourceAllocationSettingData gets registered 
before <>_ProcResourceAllocationSettingData (etc).

When the providers are unregistered, <>_ResourceAllocationSettingData is 
unregistered first because it's first in the mof file.  However, it 
can't be unregistered because <>_ProcResourceAllocationSettingData (etc) 
are still registered, so it gets left behind.

The next time you go to post install, <>_ResourceAllocationSettingData 
is already there because it wasn't cleaned up properly beforehand.

There's an ugly way to handle this in the Makefile.  I'll see if I can 
come up with a cleaner way to do this and then submit a patch.
