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.
