Looks like there has been another stab at avoiding some
unnecessary Out Of Memory killing of processes:

Author: alc
Date: Thu Jun  7 02:54:11 2018
New Revision: 334752
URL: https://svnweb.freebsd.org/changeset/base/334752


Log:
  . . .  One visible
  effect of this error was that processes were being killed by the
  virtual memory system's OOM killer when in fact there was plentiful
  free memory.
