I know, and as I said, looks like a VERY ugly way of doing that.

Yet, no package should "own", in any way, the standard directories. They
can be created form post_install of, say, base_layout, and left there
forever. Then if a package provides /usr/bin/program, only program
should be included in CONTENTS, not the /usr/bin. The .keep files
can be used during build process, to indicate directories, that
do bolong to the package, but should not be installed (better to wrap
 this by some "dokeepdir" func, to allow future change). 
During unmerge, only "owned" directories can be removed, 
and only if no other installed package uses them. A file with dir names
and usage counter can be used to track that.

Yes. run /var/qmail/bin/qmail-qstat. You'll get
about 20 unprocessed messages in the queue, while it's
actualy empty.

While you on it, consider attached qmail control script with many new
options.
Note: /init.d/svscan should be fixed not to use start-stop-daemon,
as it does not allow for more then one copy of svscan running.
It is better to run separate svscan in qmail/supervise dir then
linking qmail/supervise/* to /service, as this way you have better
control of when qmail will start.
