I see no reason to format it in Lisp. Or rather my idea is that the
status information is formated by the lisp thread in advance and sent
to the gui thread in a non-lisp format. Then the gui thread can offer
that information without contactinog the lisp thread.
Displaying that information is just a matter of formatting a native
w32 window with it.
Similar things can of course be done on other platforms, but this part
of the code is necessary platform specif (at least in the core parts
of it).

Looking at this kind of bugs is hard and requires that you have a good
enough picture of the message queue system. And just guessing what to
look at is difficult.
