In principle, I believe this could be fixed on 32-bit PA-RISC HP-UX.   
Initializer and finalizer
routines are registered by collect2 for executables and shared  
objects.  So, it should
be possible to run all destructors in reverse order of construction  
even for dynamically
loaded objects.  It's using atexit that's the problem.

64-bit HP-UX is somewhat different.  It uses .init_array/.fini_array  
but again this works
for shared libraries, etc.
