My idea was to use some Loki code for singletons and global static

I don't know Loki, so maybe I am missing something here, but I believe

we already have everything needed.
Yes, we have C++.
What do you mean? I believe that Loki is a well designed library of
good quality, but I do not see the problem that it might solve for
us. Our problem is that some global static objects are destructed too
late, because they need other objects. This problem can be solved
IMHO by putting these objects into the LyX singleton, so I don't see
why we need any additional code.
This is what I did. Hopefully, all crash-on-exit problems on windows
and Mac should be solved now.
Unfortunately, not. Quitting LyX on Mac gives:

It looks like we rely on a Qt bug on Windows and on Linux.
Bennett could you please try the attached patch.
Hum, good catch Peter. This might well be _the_ problem.
Abdel.
