messenger / ZMQ session error upon "Matlab clear all" using 'magic' #70
Description
As outlined in #56 and #69 I manage to build pymatbridge-0.3-dev under WIndows 8.1 64 bit. I can start the matlabserver and pass back and forth variables between MATLAB and my iPython notebook (Anaconda 1.9.1, Python 2.7.6) using 'magic' (the x=x+1 and a=[1,2,3]
%%matlab -i a -o b,c
b = a + 3
c = b + 3
sort of examples)
However when trying to port a more complex example,
%%matlab -o x,xf

I'd like to point out this exact snippet has been working flawlessly using pymatbridge-0.2 and the 'old' communication protocol.
I don't know if this is an issue of Windows or my build -- can pelase someone on a different OS try to replicate this behaviour?
Thanks!
EDIT: This seems to be due to the clear all; which seems to kill the matlabserver. I modified the issue title accordingly
