Although the manual sais:
``  Note that the `cleanup' attribute does not allow
      the exception to be caught, only to perform an action.  It is
      undefined what happens if CLEANUP_FUNCTION does not return
      normally. ''

Seems like somebody already thought that somebody else might
think of using 'cleanup' to catch exceptions :)

For the moment it works and I hope we can resolve this in the
next version. If the only problem is the un-freed struct
_Unwind_Exception, we can take care of it.
