I'm using 'saw' for the first time.

It seems that when a remote variable is None, then performing a pull() on
it fails.


In [2]:ipc = kernel.RemoteController(('127.0.0.1',10105))

In [3]:ipc.push
ipc.push     ipc.pushAll  

In [3]:ipc.push( 0, avar=None )
Out[3]:[None]

In [4]:ipc.pull( 'avar' )

If not a bug, this is at least a change in behavior from chainsaw, isn't
it?  I couldn't see anything to that effect in the changelog.

Thanks,
