and after all io but before actually updating the cluster chain.
Both uvm_vnp_zerorange() and vtruncbuf() call get/putpages -> bmap -> pcbmap
and here the fat cache gets updated with information no longer valid after
truncation.
The cleanup routines were being used to kill the rump process and to delete
the temporary image file. These are things automatically done by atf-run,
but it looks like this code was added here to workaround a previous bug in
the atf-run code.
Note that, in the existing form, the cleanup routines segfault (haven't
spent the time to track down why). atf-run does not care about this
(although it should), buy Kyua does.
As a side effect, this has a teeny-tiny performance speedup in the execution
of the tests including this file.

SYNOPSIS to the description of the functions.
* Use .Ss for non-standard subtitles.
* Fix two identical subtitles.
* Add missing .It's, fix few .Ft's.
* Use a little more markup.
* Improve offsets.
Instead, document saslc_sess_getmech().
* Add FUNCTIONS and describe the functions in a list for readability.
* Sort SYNOPSIS in the order of appearance in FUNCTIONS.
* Split couple of long paragraphs for readability.
* Split the code example into EXAMPLES.
* Add missing prototypes to SYNOPSIS.
* Small markup improvements.
No contextual change.
under big endian.
2. ":set octal" with nonprintable character causes nbwcurses move error.
3. moving (big)words by wW/eE/bB can't handle non-ascii characters.
4. toggle uppercase/lowercase by ~ can't handle non-ascii characters.
5. don't feed CHAR_T(=wchar_t) to is* function directly.
is* funcs with over UCHAR_MAX value may cause undefined behavior.
some ctype implementation(such as FreeBSD) return unexpected
result(same result as isw* func).
6. using non-ascii digit character with count/line number of ex/vi
command may causes unexpeced result.
