Yes that also adds to the load time, but it probably wouldn't be too 
noticeable if erlc was loading only the modules it requires instead of 
everything. I don't think it uses the network code, dets, process groups 
and so on, and it may also not need the whole OTP application framework.

I will play with generating a smaller boot file when I get the time and 
see what happens. If it can be made closer to 0s this would allow me to 
just use %.erl: %.beam rules, something that's been on my wishlist from 
the start.

Exciting thread, loving everyone involved!
