execnet-1.0.6 is a backward compatible release fixing jython/win32 and general race condition issues.
execnet is a small, stable and well documented pure-python library for automatically deploying and interacting with clusters of Python interpreters. It seamlessly instantiates remote interpreters through the 'ssh' command line tool or socket connections. It supports interactions between Python 2.4 through to 3.1, Jython-2.5.1 and pypy-c, therefore enabling generic Python-to-Python bridging.
