There was just no need for improvements -- until recently I was getting more crashes than I can analyze (i.e. run through valgrind:-).This looks rather impressive. Have you considered automatically detecting duplicates by e.g. analyzing stacktraces?
Feel free to take a look at honggfuzz - https://code.google.com/p/honggfuzz/ It provides a crude version of unification on the basis of offending program counter (as well as simple disassembly of the offending instruction). It also disables address randomization to get repeatable crashes.
