:> 
:>     I am also comitting some very strict KASSERT checking to try to catch
:>     the problem earlier.  Everyone running 4.x kernels should add the following
:
:Ahem, would you kindly define 'everyone'?

    Anyone, everyone, everybody, all ... any individual using the -4.x
    kernels needs to understand the highly experimental nature of said
    kernels.  Turning on INVARIANTS is just plain smart.   For many
    reasons but I will give you the top two:

	* The sanity checks could save your disks when someone
	  commits a major mistake.

	* The sanity checks make it easier for bugs to be found and
	  fixed when they do occur.

    -4.x is just getting on its feet, nobody should be shipping
    product with it for a while ( if they are, they are insane ).
