The only use case I think think of for the remap threads feature is if you have a plugin that can block a thread. With block, I mean, not yield it in some reasonable amount of milliseconds. For now, if you use this remap threads processor, you also have to turn off the per thread sharing of sessions, and switch to a single global session pool.


Ok, so it sounds like if something isn't blocking, then there's no need to set it at all then. My Lua code is just doing some munging on the original destination IP, so should never block. Sound right?
