execnet is a small stable pure-python library for working with local or
remote clusters of Python interpreters, with ease. It allows to make
use of multiple CPUs, connects to remote places via ssh and sockets
and requires no prior installation on remote places.
The 1.0.2 release is fully backward compatible and:
- introduces a generalized way to send channels over channels
- makes gateways more resilient against callback failures
- speeds up local gateway creation, now at <50ms on an old 1.5GHZ machine
- fixes a bug in channel.receive() which could wrongly timeout

cheers and i wish you all some relaxed last days of this decade,
changes in 1.0.2
- generalize channel-over-channel sending: you can now have channels
anywhere in a data structure (i.e. as an item of a container type).
Add according examples.
- automatically close a channel when a remote callback raises
an exception, makes communication more robust because until
now failing callbacks rendered the receiverthread unuseable
leaving the remote side in-accessible.
- internally split socket gateways, speeds up popen-gateways
by 10% (now at <50 milliseconds per-gateway on a 1.5 GHZ machine)
- fix bug in channel.receive() that would wrongly raise a TimeoutError
after 1000 seconds (thanks Ronny Pfannschmidt)
