Test for Asynchronous Eviction branch

[linmagit]

I've tested YCSB and TPCC benchmark on the asynchronous eviction branch (https://github.com/zheguang/h-store/commits/master). I'm always hitting the "failed to update tuple to new address" error. Script and example log for YCSB are in https://gist.github.com/malin1993ml/f7d5fdec21bb5fc8baa0. For TPCC, the error is similar, and the script is in https://gist.github.com/malin1993ml/8a01dc8e4cc1519f38f0.

Those scripts can run successfully on H-Store's master branch.

@zheguang could you help try my script to see whether we're getting the same error? Do you have any idea on the cause of the problem?
