The flip side of this argument is that I can't reasonably
ask customers to pull up -current sources to use a storage
product.  They've got to be able to rely on it and I've got
to be able to manage the service calls.

Eventually I'll have patches against a -stable that's close enough
to a -current that the patch will apply to both.  I'm hoping 5.3
will be this way.

This isn't news to me; I got the same thing from the linux folks.
