+/* Notes:
+ * Before you start changing something in this file be aware of the following:
+ *
+ * - There are several functions called recursively. In a very subtle and 
+ *   obscure way. DLLs can reference each other recursively etc.
+ * - If you want to enhance, speed up or clean up something in here, think
+ *   twice WHY it is implemented in that strange way. There is usually a reason.
+ *   Though sometimes it might just be lazyness ;)
+ * - In PE_MapImage, right before fixup_imports() all external and internal 
+ *   state MUST be correct since this function can be called with the SAME image
+ *   AGAIN. (Thats recursion for you.) That means MODREF.module and
+ *   NE_MODULE.module32.
+ * - Sometimes, we can't use Linux mmap() to mmap() the images directly.
+ *
+ *   The problem is, that there is not direct 1:1 mapping from a diskimage and
+ *   a memoryimage. The headers at the start are mapped linear, but the sections
+ *   are not. Older x86 pe binaries are 512 byte aligned in file and 4096 byte
+ *   aligned in memory. Linux likes them 4096 byte aligned in memory (due to
+ *   x86 pagesize, this cannot be fixed without a rather large kernel rewrite)
+ *   and 'blocksize' file-aligned (offsets). Since we have 512/1024/2048 (CDROM)
+ *   and other byte blocksizes, we can't always do this.  We *can* do this for
+ *   newer pe binaries produced by MSVC 5 and later, since they are also aligned
+ *   to 4096 byte boundaries on disk.
