[Zope-Coders] extra-clean shutdown, signal handling

[Toby Dickenson]

http://www.zope.org/Wikis/DevSite/Proposals/CleanShutdown

I would like to merge the implementation of this proposal with the trunk.=
 The=20
implementation is in toby-clean-shutdown-branch

Any objections?


(The patch currently applies cleanly to 2.6, and there are some minor=20
conflicts applying it to the trunk. I do not propose adding applying it t=
o=20
the 2.6 maintenance branch)
