Don,
I have so far testing ns_eval from the ds/shell and from there everything works as expected. I am working on making that changes to the APM.
Yes ns_eval is definitely new, and perhaps there was some question in the past of its reliability. Now that we have problems with out custom reload code, it makes sense to replace it with ns_eval, which, according to my informal testing so far, is much more reliable.
I have been using ns_eval for a year for one client to reload code on a server that is running with performance_mode_p turned on. This is great for fixing little problems in a produciton site without having to take the server down.
