| Subject: | user-defined signals can dispatch to non-existent session |
When using the kernel's signal() method to send a user-defined signal, it's possible to get a signal dispatched to a session which is in the process of shutting down (i.e. about to call the _stop event). However, the garbage collection in _data_sig_free_terminated_sessions doesn't take this into account and can cause POE to die screaming with an internal inconsistency error in _data_ses_collect_garbage.
