> is it actually pausing the capybara/rspec test such that I can have a breakpoint/debugger/REPL experience to try out various capybara/rspec code

That's a good idea. The actual method of pausing is with a ruby Queue#pop within the same thread that the actual ruby test source code is running in. I'm not sure the exact mechanism, but I assume you could run a binding.pry instead, as long as you can "cancel" it from another thread.
