Modify pages_map() to support mapping uncommitted virtual memory.

If the OS overcommits: - Commit all mappings in pages_map() regardless of whether the caller requested committed memory. - Linux-specific: Specify MAP_NORESERVE to avoid unfortunate interactions with heuristic overcommit mode during fork(2). This resolves #193.
