with new EO_LIFECYCLE_DEBUG you have these information, you can know
if the object was created, deleted and so on... then you could help
the user, not flood him with data.
See the new envvar + libeo_dbg.so (eo_debug), then you get valgrind
like information:
object was created as eoid, obj (real ptr), class... [x seconds ago]
<backtrace of creation>
object was deleted as eoid, obj (real ptr), class... [x seconds ago]
<backtrace of deletion>
object is already dead
or "object is still alive".
in the second case, you can print "but it's in a different domain".
