ok, timer is concurrent, for delay after N seconds its a bit more typing (should be some kind of helper ) ... but this is still cooperative multitasking type deal, if any one of your steps blocks, well, then it blocks :) got to this from https://metacpan.org/pod/Mojolicious::Guides::Cookbook#REAL-TIME-WEB

There might be better ways ... its best to consult mojo irc channel for that ... maybe check the logs at http://irclog.perlgeek.de/mojo
