Solving a TODO in ServerMemoryAllocator (UNTESTED)

Thanks for you contribution. A couple of quick remarks:

• The coding style is questionable. Please have a look at our coding style guidelines (for example, naming of variables). Trying not to make the code stick out would be a good start.
• Your spacing seems to be off -- we use tabs for indentation, not spaces. The spacing in the original file is okay.
• Don't leave commented out code in your patches.
• Please use a typedef for the map.
• What is "!ret_insert.second" supposed to do?
• Instead of std::pair, a dedicated structure would make the code a lot more readable.
• Areas don't seem to be deleted anymore on destruction.
• What's the point in submitting code you didn't even test?

Most issues make your patch very hard to read and evaluate.

Marking the patch as "obsolete", as pointed out by axel above, more work is required.
