i'm just guessing, but it may be related to X11's rather limited concept
of window relationships, which has propagated into GTK. if the utility
windows are marked as transients for the image window, then the
behaviour you are describing is mostly expected. X11 & GTK do not allow
a window to be a transient for several "parent" windows. 

as michael torrie noted, this is not necessary on OS X, where the idea
of an application and various different kinds of windows that it may be
using are a bit more "evolved" than the X11 situation. i am not sure
that you get the right behaviour for free, but i know that with ardour
on OS X using the native GTK port, we can (for example) make plugin
editor windows vanish when ardour loses keyboard focus and bring them
all back later, and this is a more "natural" thing to do on that
platform than it is on linux.
