[Boost-build] running tests of a python extension without deleting pyd

I'd like to build and test a python extension using bjam. How can I run
a test against a python-extension without deleting the .pyd dependency?

Based on the documentation, examples and tools/python.jam it appears
that a python extension with a unit test should be built with a Jamfile
like this:

  import python ;
  python-extension PyExt
    : # sources
      [ glob *.cpp *.hpp ]
      /boost/python//boost_python
    ;
  bpl-test testA : PyExt test/test_A.py ;
  bpl-test testB : PyExt test/test_B.py ;
  alias buildtest : PyExt testA testB ;
  explicit test_A test_B ;

However, when testA passes, the PyExt.pyd file is deleted. testB fails,
due to the missing dependency. 

Why would you ever want to have the test rule delete the .pyd?

Thanks,
