Fix for yet another subtle futex issue. The futex code used ihold() to
prevent inodes from vanishing, but ihold() does not guarantee inode
persistence. Replace the inode pointer with a per boot, machine wide,
unique inode identifier. The second commit fixes the breakage of the hash
mechanism whihc causes a 100% performance regression.
