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