I think I've fixed the windows file issues and the occasional hang (happens
when erlang fails to restart fast enough, it shut's itself down). I switched to
launching using werl instead of erl, which fixes the problem. For production
use, erl can still be used just fine, _restart isn't supposed to be used in
production.
Mark, can you verify it's fixed on your end?
