In the context of his original question, that is not right.  His original 
question was whether the callback returning FALSE avoids the need for an 
explicit final call to g_io_channel_unref() to destroy the GIOChannel object, 
assuming that before the callback returns false it only has a reference count 
of 1.

The answer is yes, since g_io_unix_add_watch(), which is called for unix 
systems by g_io_create_watch() by the io_creat_watch() callback, calls 
g_source_new() with the finalize member of the GSourceFuncs object pointing 
to the g_io_unix_finalize() function, which in turn calls 
g_io_channel_unref() - in fact that is all g_io_unix_finalize() does.

I assume the windows equivalents do the same.
