Storage Execution
There are a couple ways of going about this.
- Expose methods in WT that dumps its internal state.
- Have MDB walk Clients->OpCtx->RecoveryUnits
The latter is advantageous because it's easier to connect an OpCtx with what it was doing than a pointer to a WT session.
However, there are some gaps with walking MDB's tree. It's uncommon, but possible for recovery units to become detached as part of a "side transaction". They're temporarily stored as function locals and otherwise unable to be discovered by traversing memory structures.
If WT_CONNECTION::debug_info returned a structure, we might be able to get the best of both worlds by linking up a WT session with an OpCtx and be able to surface the dangling transactions.
