I don't mean rhetorical. I mean abstract in that it wasn't about specific locks, it was about types of lock. That's why I didn't try to name any particular functions.

The main worry expressed in the original post was about the throughput of using an IPC lock in places that don't need an IPC lock. That's the overhead I was talking about.
