I am about 99% sure that the issue involves virtual memory, not
physical, at least in the fork/exec case. The incidence of such
events under any particular system load scenario can be reduced or
eliminated simply by adding swap space.
True. When I said "a system with 1GB of memory", I should have said "a
system with 1 GB of physical memory + swap".
