Is it a requirement that the workdf process is also Jython?

If not: you could spawn a Python subprocess that hosts a Pyro4 daemon. 
Utilizing the Pyrolite java client library you can call methods in it from the 
java/jython side.  (Unfortunately it is not yet possible (due to jython 
incompatibilities) to use the full Pyro4 library on the Jython side as well). 
Not sure if it meets your set of requirements but have a look at
