i wasn't trying to show the whole thing. but your reply makes the
point i was trying to make anyway :) yes, a singleton needs to cleanup
at exit. what is "at exit"? we want it to be DLL-unload time, but can
the language ensure that this happens with a static object? the C++
working group discussion suggests that it can. however, angus has
described how OS X still has a problem in fulfilling this. as a
result, it is not possible to get the static object to be cleaned up
at the correct time by relying on language features. hence, the
discussion.
