Subject: Fix state checks on liveness handling.
X-Git-Tag: tor-0.2.2.17-alpha~9^2~7
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0744a175afa559435bd0e3cdb53891282469e0ee;p=thirdparty%2Ftor.git

Fix state checks on liveness handling.

If we really want all this complexity for these stages here, we need to handle
it better for people with large timeouts. It should probably go away, though.
