On julia 0.5 and tagged version of the package, this goes into an infinite loop:

julia> x = dones(5000,5000);
julia> @time x';

I can't reproduce this bug. I'm running DistributedArrays v0.2.0 on Julia 0.5.0-dev+3928

@ViralBShah I also don't see this. Do you still have this issue?

I see the issue. Even with one processor on Julia 0.4 on my mac, it is very slow:

julia> a = drand(1000,1000);

julia> @time a';
  6.344167 seconds (40.76 M allocations: 1.010 GB, 2.48% gc time)
