The main reason for overcommit is the use of copy-on-write when
creating writable mappings, particularly with regard to fork().

When a process fork()s, the process' (virtual) memory is duplicated. Once
upon a time, the memory was literally duplicated; modern systems use
copy-on-write instead.

On older systems, fork() would fail as a matter of necessity if there was
insufficient memory for duplication. With copy-on-write, failure isn't
necessary, and would usually be gratuitous as most processes exec()
shortly after the fork(), without having modified a significant proportion
of the memory.

So modern systems typically don't care whether or not you have enough
virtual memory (physical memory plus swap) for duplication; they just
assume that it won't be necessary, and most of the time that assumption is
correct. Unfortunately, if the assumption isn't correct, you only find out
when the child process modifies one too many copy-on-write pages.

One alternative is to simply disable overcommit, which means that you
cannot spawn any child process unless the system has sufficient free
memory to duplicate all of the process' writable memory.

Another alternative is to use vfork(). Unfortuntely, vfork() has a history
of non-portability (it has been removed from POSIX, mainly because no
platform which provided it actually followed the POSIX semantics), and is
often too limited to actually be useful (e.g. the child process isn't
supposed to call anything besides exec() or _exit(), so no dup(), no
sigaction(), no printing error messages, etc).
