During SERVER-71198 we uncovered that the deadlock described by SERVER-71191 and SERVER-44722 could theoretically occur during index cleanup in a rollback.
Running resmoke with --suite=replica_sets jstests/replsets/rollback_index_build_start_abort.js and the attached patch will yield an invariant error. The following two lines from this backtrace are relevant:
