This isn't 4.4.0-rc6 but it has diffs that were merged after rc5 and should be in rc6. I used a build with this diff and the binaries from here
The good news is that it might have fixed WT-6164 as I have yet to reproduce an OOM on shutdown. The bad news is that I get a new problem – an intermittent hang on shutdown.
From mongod.log, the start of shutdown

Then lots of this

Then this, once
{"t":{"$date":"2020-05-14T18:05:31.000+00:00"},"s":"I", "c":"STORAGE", "id":22430, "ctx":"WTCheckpointThread","msg":"WiredTiger message","attr":{"message":"evict generation drain waited 1 minutes"}}
Then this forever

And these occur, but less frequently
