Offhand, the knee-jerk reaction is that if enabling range stepping causes a regression, then it sounds like range stepping has a problem that should be fixed and it may be premature to enable it. I see a parallel here with all the all-stop-on-top-of-non-stop work, which exposed a ton of such latent problems that were treated as dependencies that needed to be addressed first. That's what resulted in the creation of this test (see 'git log ede9f622af1f'). as-ns is enabled by default on native, but not on remote. It sounds like testing with as-ns enabled on remote could reveal the same range stepping problems, but all over the testsuite instead. :-/ Thanks, Pedro Alves
