As Platonides says there is no system method for locking .. web locking is a very difficult thing to do.
There are a couple of templates available, I think on wikipedia, inuse and underconstruction.
We use the inuse template for this purpose

Hi,
Is there any provision to lock editing of an article for others while one person is editing that article?
i.e. if one person is editing an article, any other person trying to edit that article should get a message that it's being edited by another user.
Edit conflict feature may be confusing for not-that-techno-savvy users :(
