Not necessarily.  X/Motif is asynchronous and SWT runs there.  We don't realize on Motif until
the shell is shown or we are force to do so to either work around a bug or implement an API that
needs to reach through to get X resources.  I am planning to take the same approach for GTK.

BTW: g_log is great.  We've already used it to hunt down a missing "ref".
