locking against myself in getcacheblk()?

[Matthew Dillon]

    I'm testing a revised version of the patch now and should be able to
    commit it in a little bit.  Basically the same thing (you may have
    gotten that token lock/unlock that broke the direct patch wrong when
    you manually patched it), except I adjusted the b_refs check in
    getnewbuf() as well to prevent an invalidation race.
