Comment (by nickm):

 Note from IRC: I like the idea here as a band-aid. I think that the
 maximum should be configured via a consensus param, though, and default to
 something a bit higher than 1000?

 Also I really want to know what Roger thinks of that idea.

 In the long term, we're not going to get long-term fixes for the
 performance issues caused by being low on memory of this until we can
 better identify memory pressure: either by setting MaxMemInQueues more
 aggressively, working with the OS/allocator somehow, asking the user to
 configure MaxMemInQueues to a lower value, or something like that.
