* optionally call Gio::Initable::init() instead.
*
* When the initialization is finished, @a slot will be called. You can
* then call init_finish() to get the result of the initialization.
*
* Implementations may also support cancellation. Initialization can be
* cancelled by triggering the @a cancellable object from another thread. If
* the operation was cancelled, the error Gio::IO_ERROR_CANCELLED will be
* returned. If the object doesn't support cancellable initialization, the
* error Gio::IO_ERROR_NOT_SUPPORTED will be returned.
*
* If this function is not called, or returns with an error, then all
* operations on the object should fail, generally returning the error
* Gio::IO_ERROR_NOT_INITIALIZED.
*
* Implementations of this method must be idempotent: i.e. multiple calls to
* this function with the same argument should return the same results. Only
* the first call initializes the object; further calls return the result of
* the first call. This is so that it's safe to implement the singleton
* pattern in the GObject constructor function.
*
* For classes that also support the Initable interface, the default
* implementation of this method will run the Gio::Initable::init() method
* in a thread, so if you want to support asynchronous initialization via
* threads, just implement the AsyncInitable interface without overriding
