Memory management documentation

[Ali Çehreli]

Some of the examples at

   http://digitalmars.com/d/2.0/memory.html

seem to be outdated:

- dmd 2.046 does not have std.outofmemory. Where is OutOfMemoryException 
defined?

- no std.gc: (I found out later that core.memory is it)

Where can I learn more about the current features on memory management.

Thank you,
Ali
