13 * Before you start changing something in this file be aware of the following:
15 * - There are several functions called recursively. In a very subtle and
16 * obscure way. DLLs can reference each other recursively etc.
17 * - If you want to enhance, speed up or clean up something in here, think
18 * twice WHY it is implemented in that strange way. There is usually a reason.
19 * Though sometimes it might just be lazyness ;)
20 * - In PE_MapImage, right before PE_fixup_imports() all external and internal
21 * state MUST be correct since this function can be called with the SAME image
22 * AGAIN. (Thats recursion for you.) That means MODREF.module and
