This has changed, and I need to make it clearer in the documentation.  There
is no longer a global "disable all __before_traverse__ hook" URL.  Instead,
there are specific SiteAccess object-disabling environment variables.

You need to start Zope with environment variable SUPPRESS_ACCESSRULE set.
There is a similar SUPPRESS_SITEROOT variable for SiteRoots.

Fire up a command shell and type (*nix):

SUPPRESS_ACCESSRULE=1
export SUPPRESS_ACCESSRULE

or (Windows):

set SUPPRESS_ACCESSRULE=1

...and then whatever command you use to start Zope

That's because the fundamental mechanism is built into Zope 2.2, rather than
grafted on by SiteAccess 2.  It does look like we'd better wrap the hook
call in a try..except pass, though.
