      Description

      tryToGoLiveAsASecondary needs to take a write lock. Otherwise, we could become primary between lines 562 and 590 of rs_sync.cpp and then immediately become a secondary, not closing connections if anyone is syncing from us (which they may have been simply doing already through chained replication).
