    Quite possibly, but if it does not introduce any new bugs I will
    probably want to commit it anyway.  I just think it's too dangerous
    to try to reuse an inode that has not yet been completely disposed 
    of, especially with softupdates active.  It's also possible that it
    might improve performance.  With dirpref active inodes are far more
    likely to be reused quickly and this avoids a blocking condition in
    VGET by avoiding inodes that are in the process of being destroyed.
