caused trouble with backward compatiblity. The content of the __init__.py is
necessary for pre-2.6 installation but no longer used in 2.6.

better performance for higher end machines (that are more likely to be in
use in production systems).

Caused the meta-signal-handler method to log when a registered handler fails.  Also fixed a bug in logfile rotation.

A couple of documentation and formatting cleanups.

reported errors about this; hopefully it will now work again (if they
use setup.py for their build).

with an alternative that works under command.com too.  Building the
splitters still fails on command.com systems because the synthesized
command lines are very long (command.com appears to truncate them,
leaving gibberish commands).

Reimplemented Index.length to use a BTree.Length. Previous dynamic computation was way too slow for big indexes.
Updated tests to include length value checks

so makes the full suite brittle.  Cleaned out all the places where unit
tests change sys.path.  (Use the PYTHONPATH environment variable instead.)

Also brought SearchIndex tests up to date, which I didn't really need to do
since SearchIndex is deprecated, but I did it as part of figuring out the
failed Interface tests, so I might as well check in my work. ;-)  One of the
test modules in SearchIndex forgets to define a global named "Dummy",
actually, so all the tests were failing before this checkin anyway.

All Zope process will respond to signals in the specified manner:

  SIGHUP -  close open database connections and sockets, then restart the
            process

  SIGTERM - close open database connections and sockets, then shut down.

  SIGINT  - same as SIGTERM

  SIGUSR2 - rotate all Zope log files (z2.log, event log, detailed log)

The common idiom for doing automated logfile rotation will become:

kill -USR2 `cat /path/to/var/z2.pid`

The common idiom for doing "prophylactic" restarts will become:

kill -HUP `cat /path/to/var/z2.pid`

When a process is interrupted via ctrl-C or via a TERM signal (INT, TERM),
all open database connections and sockets will be closed before
the process dies.  This will speed up restart time for sites that
use a FileStorage as its index will be written to the filesystem before
shutdown.

Unspecified signals kill the process without doing cleanup.
