Backtrace of KDevelop 4 C++ parser when running more than one thread at a time

Hi Adam!
Adam, you can't share the `memory pool' :-) The `memory pool' needs to saved
and stored with the TranslationUnitAST and the TokenStream. That means you
need a different `memory pool' for each parser. Please, remember that the AST
nodes are allocated in the `memory pool' :-)
