I'm guessing Cho meant: "This isn't an academic exercise - I have a
real use case that requires reference counting."

Cho needs to be more specific about his "Some driver needs enabling
sysmmu" example. Then others would understand why/when the reference
counting is needed. Ie walk through a real driver that exists today
that depends on reference counting.

cheers,
