On TestRPC, I'm seeing a particular transaction that is taking 47275 gas instead of the predefined 47155. It's not at all obvious to me why this transaction is taking an extra 120 gas, and I've been unable to reproduce the issue in the 0x.js test suite, but bumping the gas allowance has resolved the issue for me. The transactions in question are trying to set an unlimited proxy allowance on either the WETH or ZRX tokens in the testrpc snapshot, but run out of gas.
