If you don't want to run with overcommit you turn it off. At that point
processes get memory allocations refused if they can overrun the
theoretical limit, but you generally need more swap (it's one of the
reasons why things like BSD historically have a '3 * memory' rule).
So sounds to me like a problem between the keyboard and screen (coupled
with the fact far too few desktop vendors include tools to easily set
this stuff up)
