There were indeed a couple of (obscure) issues with the Jython/Windows combo. 
I think i fixed those now.  Could you try 'easy_install' or 'pip' with the
following URL: 

http://hudson.testrun.org/view/pytest/job/execnet-sdist/lastSuccessfulBuild/artifact/dist/execnet-1.0.6.tar.gz

and report back if it becomes useable for you on Jython/Windows? 
I'd then see to release this as a 1.0.6 soon. 

cheers,
holger
