  25 # This unit test verifies that multiple interposing libraries can all
  26 # interpose the same function and the result is that they chain together.
  27 # That is, each one calls through to the next.
  28 #
  29 # On Tiger (10.4.0), this test fails with infinite recursion.
  30 #
  31 # The function foo() does string appends.  This allows us to check:
  32 # 1) every interposer was called, and 2) they were called in the
  33 # correct order.
