Note that our private runs use some freebsd-specific models that 
eliminate many false positives in the analysis runs.  This means, for 
the kernel at least, that the results may be misleading.  We also have 
some issues that inflate the reportage somewhat and we're working with 
Coverity to resolve them.

OTOH we've done nothing with user application code and based on the work 
I've seen done by netbsd there's plenty of stuff to be fixed there.  So 
if you want to help out get an account and start feeding back fixes for 
the user code.
