commit 7a374dd4446543339eee75421fbc1af73aa2c011
Author: Philipp Winter <phw at torproject.org>
Date:   Mon Mar 3 23:10:51 2014 +0100

    Only search for mark in expected space.
    
    We know in which array slice the mark is expected.  As a result, we don't have
    to look any further than that.  Patch by Yawning Angel.  See the following
    ticket for reference: <https://bugs.torproject.org/11092>.
