Further to this, if I delete the wait() before the print "2 ..." then
2 and 3 work fine, with ret code 0.  4 fails in threading as
expected.  Here's the output in this case:

13/01/2012  08:55            33,213 _testcapi.dll
13/01/2012  08:55            12,103 _weakref.dll
            183 File(s)     44,408,313 bytes
              2 Dir(s)  56,063,664,128 bytes free
1. return code:  0
2. return code:  0
3. return code:  0
