/**

|
* This test creates replica set and then puts load on the primary with writes during
|
|
* the initial sync in order to verify that all phases of the initial sync work correctly.
|
|
*
|
|
* We cannot test each phase of the initial sync directly but by providing constant writes we can
|
|
* assume that each individual phase will have data to work with, and therefore be tested.
