That means baloo_file has opened the same env twice in the same process

We've expanded the logging to include PIDs so we can more definitively show what's happening. But the problem remains:

... Process 514137 has an active write transaction, but process 594170 successfully opens a new write transaction. That can only happen if LMDB's write mutex has been removed out from under it.

So it actually never was an duplicated open from the same process, but multiple opens from different processes, correct?
