 Description   

mr_during_migrate.js recently failed when performing a query (find command) on a sharded collection.

The error appears to be a leaked SCE, which can only happen if mongos gets 5 SCEs in a row. As the operations in the test are not guaranteed to complete, we should wrap them in a retry loop of some sort (or rewrite the test as it is not guaranteed to complete).
