-----------------------------+----------------------------------------------
The IO manager registers two file descriptors with the RTS which the RTS
uses to send control and wakeup signals to the IO manager. The main IO
manager is started up by default and registers some file descriptors that
it has allocated with the RTS.
The base package also exposes a GHC.Event module which when initialized
will also register files with the RTS, overwriting the main IO manager's
files. Now the RTS can no longer signal the main IO manager.
