CuArray allocation issue: How often is it a problem?

Hi there, I’m thinking about making use of Flux and CuArrays for a new project. However, I was a little troubled to learn about this issue. It’s hard to a get a sense from that thread how often this is coming up as a problem for people. How many other folks are pushing CuArrays to a similar limit? How many folks have done so and run into this problem? Has anyone run into anything similar with KnetArrays using Knet? (On a related note, how realistic is it to use KnetArrays as part of a Flux model? Is that possible?) Just looking to get a sense of what I am walking into.
