I do not believe : this is true. I believe that fork can cause an overcommit too. Likewise, : even simply running multiple copies of the same executable causes an : overcommit case. : : This may solve something, but it's not the general overcommit problem. It solves the ANSI C compliance problem, which is one whose significance I understand fairly well, although I do not have to deal with it myself. ANSI C doesn't specify the behaviour of fork.
