Method _handle​Signals Extend the basic signal handling logic to also support handling SIGCHLD to know when to try to reap child processes.
Method _remove​All Remove all readers and writers, and list of removed IReadDescriptors and IWriteDescriptors.
Method _uninstall​Handler If a child waker was created and installed, uninstall it now.
Class Variable _supported​Address​Families Undocumented
Instance Variable _child​Waker None or a reference to the _SIGCHLDWaker which is used to properly notice child process termination.

Inherited from _SignalReactorMixin (via ThreadedSelectReactor, PosixReactorBase):

Method start​Running Extend the base implementation in order to remember whether signal handlers should be installed later.
Method _really​Start​Running Extend the base implementation by also installing signal handlers, if self._installSignalHandlers is true.
Instance Variable _install​Signal​Handlers A flag which indicates whether any signal handlers will be installed during startup. This includes handlers for SIGCHLD to monitor child processes, and SIGINT, SIGTERM, and SIGBREAK to stop the reactor.

Inherited from _DisconnectSelectableMixin (via ThreadedSelectReactor, PosixReactorBase):

Method _disconnect​Selectable Utility function for disconnecting a selectable.
