| Subject: | _child(lose) event fired for a session detached from its parent |
When a session is detached from its parent in its _start event
(POE::Kernel->detach_myself), no _child events should be fired to the
session which called the POE::Session->create constructor.
Currently no _child(create) is fired. This is good.
But a _child(lose) is fired. This is unexpected. And inconsistent as we
are in a case where we have a _child(lose) without a corresponding
_child(create/gain).
This bug has been discussed on the mailing list on 2009-11-19.
A complete test case is attached.
Verified on POE 1.006 and 1.280 ( other releases not tested).
