/**
* Listen for IPC connections

* The supplied handler is passed on to incoming instances of IpcConnection. When
* a connection is first opened, it is called with IPC_EVENT_NEW_CONNECTION. The
* receiver must take ownership of the connection object. When a connection is
* closed, IPC_EVENT_CONNECTION_CLOSING is generated. At this point (or after) the
* receiver must delete the object. IPC_EVENT_COMMAND is generated when lines of
* text are read, and in this cases the last argument is not NULL. No closed event
* is generated in the event of manual delete if the connection is still open.
*
* Yeah, this whole callback model sort of sucks. Might rethink and replace with
* some kind of actor model or something if it gets too unweildy. But for now the
* use cases are simple enough that it's not too bad.
*
* @param commandHandler Function to call for each command
* @param arg First argument to pass to handler
* @throws std::runtime_error Unable to bind to endpoint
