If you wish to make an edit without being disturbed, you should add the Template:In Use to the top of the article, which has been designed precisely to avoid these kind of things happening.

Also, if there is an edit conflict, before closing the page, the system warns you, and allows you to copy your versión of the edit, which of course, after closing, is forever gone...
