Taking a good look at the code i just changed the isolated = true to false,
so it would call the make_persistent_loader instead of the isolated. It
worked fine just as i expected, still don't know why with isolated = true it
reloads the script when returning a 4XX or receiving a DELETE.
I'm working with only one script, so the problem seems resolved to me.
Sorry for the noise.
