nsim works fine with ipyparallel 4 and earlier, but gives spurious messages with ipyparallel 5.0.x and breaks with ipyparallel >=5.1.x, working some of the time, and completely freezing with no error message at other times. See mattja/distob#3.
Have not yet investigated this to find whether this is a bug in ipyparallel or distob, or whether it results from a change to the AsyncResult interface in ipyparallel.
Until this issue is sorted out, temporarily require ipyparallel 4.x
