Err.. Yes - you're right. I need to check the spec to see if this is
what indeed is required.

string_mgr definitely needs to not free anything in the destructor
(since CORBA_free on a variable length struct or sequence also deep
frees the contents). I'm not sure if it also needs to initialise to an
empty string - it depends on whether the C marshallers can cope with
NULL strings in sequences and structs.
