  23 /* Notes:
  24  * Before you start changing something in this file be aware of the following:
  25  *
  26  * - There are several functions called recursively. In a very subtle and
  27  *   obscure way. DLLs can reference each other recursively etc.
  28  * - If you want to enhance, speed up or clean up something in here, think
  29  *   twice WHY it is implemented in that strange way. There is usually a reason.
  30  *   Though sometimes it might just be lazyness ;)
  31  * - In PE_MapImage, right before PE_fixup_imports() all external and internal
  32  *   state MUST be correct since this function can be called with the SAME image
  33  *   AGAIN. (Thats recursion for you.) That means MODREF.module and
  34  *   NE_MODULE.module32.
