  12 /* Notes:
  13  * Before you start changing something in this file be aware of the following:
  14  *
  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 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
  23  *   NE_MODULE.module32.
  24  * - Sometimes, we can't use Linux mmap() to mmap() the images directly.
  25  *
  26  *   The problem is, that there is not direct 1:1 mapping from a diskimage and
  27  *   a memoryimage. The headers at the start are mapped linear, but the sections
  28  *   are not. Older x86 pe binaries are 512 byte aligned in file and 4096 byte
  29  *   aligned in memory. Linux likes them 4096 byte aligned in memory (due to
  30  *   x86 pagesize, this cannot be fixed without a rather large kernel rewrite)
  31  *   and 'blocksize' file-aligned (offsets). Since we have 512/1024/2048 (CDROM)
  32  *   and other byte blocksizes, we can't always do this.  We *can* do this for
  33  *   newer pe binaries produced by MSVC 5 and later, since they are also aligned
  34  *   to 4096 byte boundaries on disk.
