via mmap() up around the shared library area. Previously the directory
was allocated from space from it's own memory pool. Because of the way it
was being extended on processes with large malloced data segments (ie: inn)
once the page directory was extended for some reason, it was not possible
to lower the heap size any more to return pages to the OS.
(If my understanding is correct, page directory expansion occurs at 4MB,
12MB, 20MB, 28MB, etc.) I was seeing INN allocate a large amount of short
term memory, pushing it over the 28MB mark, and once it's transient demands
hit 28MB, it never freed it's pages and swap space again.)
I've been running this in my libc for about a month...
Also, seperate MALLOC_STATS from EXTRA_SANITY.. I found it useful to call
malloc_dump() from within INN from a ctlinnd command to see where the hell
all the memory was going.. :-) I've left MALLOC_STATS enabled, as it has
no run-time or data storage cost.

The code, as written, appears to load the new database data into a new
hash file and renames the two.
Due to a run of bugs and lack of error checking, it's going a whole
mess of unlink() and rename() calls that are failing. It only
worked in the first place because the data was being inserted into a
"live" hash file. (I wonder how much stale data has assumulated?)

Note that this code is dormant unless the options files exist.
Also, parsing of quoted options in the config files is improved.
What this allows, is all the options in LINT to be specified to be
configured as #defines in a file rather than on the CC command line at
kernel build time. This means that 'make depend' will catch dependencies
on actual *options*, meaning that you can run 'config' and 'make depend'
in complete safety WITHOUT removing the compile directory each time.
Unfortunately, this requires a pass over the source to get the individual
files to #include the new .h files that would be generated by config.
This has a small compile time penalty (appears up to about 2% slower)
from a "fresh" build. Of course, you should not be needing to do complete
rebuilds very often once this was completed, so it would be an overall
win for most people.
Since this code is dormant and we've got a lot of other things happening
on the kernel tree at the moment (prototypes, devfs, static declarations
etc) I am not planning on doing any changes to activate this feature just
yet.
the 'rm -rf' and cpio was bugging me because rdist used to get false hits
and also it installs the files with the wrong uid.
I've tried this by running a find .. -exec ${INSTALL} ...; instead...
plus a couple of minor changes..
Some highlights of the new stuff that was not in the old version:
- remote access support.. full checkout/commit/log/etc..
- much improved dead file support..
- speed improvements
- better $CVSROOT handling
- $Name$ support
- support for a "cvsadmin" group to cut down rampant use of "cvs admin -o"
- safer setuid/setgid support
- many bugs fixed.. :-)
- probably some new ones.. :-(
- more that I cannot remember offhand..

Most drivers use nullreset but noreset has the advantage of complaining
