  27 ### This test case is to verify that dyld cannot be tricked into loading
  28 ### the "same" library twice.
  29 ###
  30 ### The tricky scenario is:
  31 ###  1) a library dyld is to load is specified with a symlink path
  32 ###  2) the library the that is the target of the symlink is already loaded
  33 ###  via a different path.  In this case becuase of DYLD_LIBRARY_PATH.
