Summary: Added a warning to the log. Every 3 seconds (let's not make that configurable). Can be turned off. I still don't like this. We are raising another thread and reading a file to do monitoring. We're developing a DB, not a sys monitor. Serious admins do that themselves. But, here it is. UPDATE: Cleaned up `utils/sysinfo/memory`. Removed all unused functions. Removed the faulty memory check in `tests/concurrent`.
