I don't get it.  The comment claims we have to _hash_getnewbuf before
releasing the metapage write lock.  But the function neither calls
_hash_getnewbuf nor releases the metapage write lock.  It then goes on
to say that for this reason we pass the new buffer rather than just
the block number.  However, even if it were true that we have to call
_hash_getnewbuf before releasing the metapage write lock, what does
that have to do with the choice of passing a buffer vs. a block

Explain to me what I'm missing, please, because I'm completely befuddled!

(On another note, I committed these patches.)
