reference count was transferred to the new object, but both the
new and the old map entries had pointers to the new object.
Correct this by transferring the second reference.

get it in the CVS logs. This pertains to rev 1.30 (and the MFC of it):
Space optimization forces the kernel to always use fragments to store
parts of file, rather than using an entire block when less than an
entire block has been written. This forces files to be as small as
they can be at the minor cost of time to do all the fussy stuff. The
cpio image that we put on the disk was so close to filling the disk
exactly that this minor minor difference made a big difference. The
system changed things to time optmization on the first write. When
the end of file was hit, it tried to allocate a full block (4k), but
there was only 3k left on the disk (since you get only 1407 blocks on
a 1.44 floppy) so it failed. So this change nails the space
optmiziation in place for the whole operation.

variable instead of MAXTTL constant as the default time-to-live
value for outgoing IP packets all over the place, as we already
do this for TCP and UDP.

if we hold a spin mutex, since we can trivially get into deadlocks if we
start switching out of processes that hold spinlocks. Checking to see if
interrupts were disabled was a sort of cheap way of doing this since most
of the time interrupts were only disabled when holding a spin lock. At
least on the i386. To fix this properly, use a per-process counter
p_spinlocks that counts the number of spin locks currently held, and
instead of checking to see if interrupts are disabled in the witness code,
check to see if we hold any spin locks. Since child processes always
start up with the sched lock magically held in fork_exit(), we initialize
p_spinlocks to 1 for child processes. Note that proc0 doesn't go through
fork_exit(), so it starts with no spin locks held.

- Remove the BUGS section as all the bugs listed have been fixed now.
This is needed even with `-o space' as the kernel decides to be "helpful"
and not really do space optimization. Looking at src/sys/ufs/ffs/ffs_alloc.c
we see why: if (fs->fs_minfree <= 5 ||
fs->fs_cstotal.cs_nffree >
(off_t)fs->fs_dsize * fs->fs_minfree / (2 * 100))

I have picked `1' vs. `0' just incase some code somewhere has the assumption
the %free can never be `0'.
