These are edge cases we've discovered in our implementation, adding them to the fuzzer could expose bugs. |

We will get some coverage of multi-key writes within transactions being rolled back as part of the work on This ticket would cover adding multi-key writes outside of transactions, and background index builds (which we wait to complete before starting rollback). But we think the value of testing those scenarios is relatively low. |

Per conversation with robert.guo, the rollback fuzzer already does background index builds, but since there is only one client, those essentially are foregrounded on the primary. ( See https://docs.mongodb.com/v3.6/core/index-creation/#behavior). We should add the ability to run multiple clients, or at least one off parallel shells for background index builds, to the fuzzer.
