should have same number of elements and terminated with zero. We violate
this, since FirstThunk points directly into machine code. But in practice,
- OS loader implemented the sane way: it goes thru OriginalFirstThunk and

puts addresses to FirstThunk, not something else. It once again should be
noted that dll and symbol name structures are reused across fixup entries
and should be there anyway to support standard import stuff, so sustained
