Please indent the IPC_MESSAGE_HANDLER and IPC_MESSAGE_UNHANDLED macros by one
block.

Done.

Please attribute your TODOs (this is different from Blink's FIXMEs, which are
unattributed).

[Peter Beverloo, 2014/04/01 14:53:18]

Should we perhaps post a task to call DidRegister with an error code?  That
would at least allow a round-trip between processes, which can be convenient for
testing at this stage.

[Michael van Ouwerkerk, 2014/04/02 14:25:15]

Done.

[Michael van Ouwerkerk, 2014/04/02 14:25:15]

Done.
