I'm only doing this for Zope at this time, because it was the
worst abuser wrt checking in zdaemon changes from a wrong place.
Only one wrong-place zdaemon checkin was made from Zope3, and
none from ZODB.  Nevertheless, all trunks and branches other
than Zope trunk are using an out-of-date zdaemon now.

Instead of poke-and-hope guessing at how long to wait
for the child process to start running, use send_action()
in a loop to ask about that more directly -- but don't
wait longer than a minute.

The test should run faster on most boxes now, but
take up to a minute on boxes that are bogged down for
whatever reason.

Note that this checkin is being made from a wrong place!
zdaemon isn't part of the Zope tree, it's stitched in
from the zdaemon repository.  So this checkin has no
effect on zdaemon.  It will need to be sideported later
if it turns out to fix the overnight test failures.

fix for testRunIgnoresParentSignals.

testRunIgnoresParentSignals occasionally fails.

ZODB cache size is an integer (number of objects), not a number of bytes.

Because this change wasn't made in ZODB (the right project), it got
lost when I stitched in ZODB 3.3.1a1 yesterday.

      - Collector #1655: fixed severe memory leak in TemporaryStorage

Work around for MSIE WebFolder view not properly showing modified and created date.  This is the same thing that Apache DAV does, FWIW.

No commit message

A RNFR (rename from) request was always responded
with a response 350 (succesful). We do now check if the 
source file really exists and return a 550 response in case
if it doest not.

Collector 1626: Don't raise Forbidden if we don't know what to do.  Instead, riase Unauthorized if _verifyObjectPaste fails in a way that we understand; let all other exceptions bubble to the top.

        full URL without query string as it appears within the location bar of
        the browser. The key has been added to provide a single key that is 
        available for vhosted and non-vhosted installations.

      - Collector #1605: VHM did not quote URLs

      - webdav.Resource: during COPY, manage_afterClone was called way
        too early, thus the object wasn't bound to the database and
        couldn't find a context. Changed to behave the same way as
        CopySupport.

      - RAMCacheManager: opimized performance by using cPickle instead
        of pickle and by using the highest pickle protocol available
        instead of using ASCII pickles (patch by Dieter Maurer)
