Is there a reason to skip the complete termination?

Well, in #125, you suggest :

I'd prefer the second - and document that modules will only be unloaded with this function if after the call a manual call to cob_tidy() is done.

Since cob_tidy calls call_exit_handlers_and_terminate, it seemed natural to just skip the whole termination.

Anyways, I pushed an improved version, where only the last bits of termination are delayed, ie only the following calls :

    cob_exit_call ();
    cob_exit_common ();

Cleanup is automatically performed after the longjump, so no need to call cob_tidy.
