Other performance bits:

• Vague linkage cripples us

• • all shlib components loaded RTLD_GLOBAL
  • compile & link: 1 monster 'libexcept.so' => RTLD_LOCAL
  • • 40% linking speedup (~700ms)

• • Code size redux:
  • • Splitting out dialogs:
    • • aggregation not inheritance.
  • Sharing exception data
  • • COMDAT (?)
  • Better linking:
  • • vtable copy logic, & via-vtable / parent chaining.

• 64bit support

• • don't load lots of 32bit libraries to launch OO.o ...
