/*

This script is a hack that provides delayed loading for content buffers.
The initial url of a buffer will not be loaded until that buffer is
switched to.  Precaution is taken that the buffer's display_uri_string
returns the delayed url, not about:blank, so things like tabs and sessions
will still work properly.
