This is what I did.  However, the solution is less elegant than I
could have wished.

I've organized the libwww/Qt wrappers as two classes that have
singleton instances created as automatic variables in main(), and the
order they're created in determines the reverse order they're
destroyed in.

The LibwwwNotify class interfaces libwww events and timers to their Qt
equivalents.  The W3CLibwww class wraps libwww initialization and
shutdown.  The LibwwwNotify instance has to be created before the
W3CLibwww instance, because the latters destructor will try to
unregister any timers still left, and this crashes if the LibwwwNotify 
has gone away.

What I did was add a registerHandlers() method to LibwwwNotify, and
call it after the W3CLibwww was created to re-register the
LibwwwNotify register/uregister functions.

My thoughts exactly.

Hm... this is an idea.  I will investigate further.

Thanx!
