namecache stage-2 patch for testing

[Matthew Dillon]

:Testing of NAMEI2.DIFF with compares of without.
:All of the testing without used kernel as of Sep 24.
:The testing was performed in this order on both occasions.

:-DR

    Uh.  Try removing the debugging printf()'s in the patch I posted
    and re-run your compare.  The patch is not meant to be a performance
    patch, but it should yield comparable times.
