 It'll take a little time to write this change. And, it's low level
and important code, so it will take a time to test the stability
before sending pullup request. So,

 0) Apply the following change to -current.

 1) Sent the pullup request to netbsd-8

 2) Write auto-resize code and commit.

 3) If it's stable, send the pullup request to netbsd-8.


 OK?
