And  user->name = new_stringw(L"User"); will do so as well

(In this example, it grows by about 1 mB every 5 seconds.) I cannot see the memory leak when
testing with valgrind, so it would suggest that the leak is in Etch managed memory which is
cleared at exit.

Can anyone comment on the potential cause of the memory consumption?
