CORBA34 — Potential deadlock with POA::deactivate_object()

The draft CORBA 2.3 spec (ptc/99-03-07) does not deal with a potential deadlock situation. If an object is explicitly deactivated with POA::deactivate_object(), the object remains in the active object map until all operations pending on the object have completed. Any attempts to reactivate the object (implicitly via a ServantActivator, or explicitly via activate_object_with_id()) must block until the pending invocations have completed. However, if a servant's implementation of an object deactivates the object and then (directly or indirectly through a call to another collocated object) reactivates the object, the invocation will deadlock.
