I did not run into a scenario where this prevented a test from properly failing or passing during my testing. It appears it would be very uncommon to run into this.

This created an environment where the CEL events would not always be in the same order upon each execution. Specifying a partial order on some of the requirements allowed to successfully work around the CEL events not being in the same order thus allowing the test to pass. Used it to also ensure expected failures did in fact cause the test to fail.
> * Tested by modifying the bridge/bindxfer_nominal/ test (which actually performs a blind transfer) to use this and again was able to use the partialorder on some of the requirements to work around the CEL events not always being in the same order.

> * Tested to ensure that only those EventName's listed in the requirements are checked and those not are ignored.
