The results are still not as expected. This change seems to be the cause 
of the new Python errors. The symptom is that on a single tester running 
multiple toolsets causes errors like:

Run output [2006-11-17 22:21:57 UTC]:

C:\Python\2.3\python.exe: can't open file '..\libs\python\test\args.py'

EXIT STATUS: 2

What I observed when trying to replicate this is that doing:

cd libs/python/test
bjam --v2 toolset=msvc-8.0 args
bjam --v2 toolset=msvc-8.0 args

Causes the second bjam invocation to fail with:

error: Unable to find file or target named
error:     'args.py'
error: referred from project at
error:     '.'

This is because the first bjam invocation succeeded and deleted the 
"args.py" file! To say the least this is not good :-) According to Dave 
it should be delete the "args.pyd" file which is the module it 
generated, not the python program.
