The deadlocks described in SERVER-71191 and SERVER-44722 are caused because the following conditions are true, in general
- An operation is unkillable by stepdown
- While holding the RSTL in IX mode, an operation takes an X collection lock. If there are any prepared transactions, this blocks.
- The stepdown thread tries to acquire the X lock, but blocks because of a conflict
In this situation, the operation that isn't interrupted by stepdown does not make progress. We should add an assertion to our lock helpers that prevent unkillable operations from taking X locks while also holding the RSTL.
