[erlang-questions] Fire and Forget

Thanks Paul. It was more that as i would be just logging lots of data,
if some gets lost it is ok, hence it doesn't need to wait on a 200.

So, I guess it was how to optimise under those conditions, but perhaps
doing an async post and later getting a 200, even if it is just a "all
is ok" even if i don't intend to do anything beyond that may be a
sensible approach anyway.

Restart temporary under supervisor sounds good - i mainly don't want
to block anything. Unfortunately I come with the burden of years of
procedural programming so my mindset is still adjusting to the fact
spinning up many processes is a good thing in erlang.

It may be I should be passing the data using something other than an
HTTP POST and more erlang-like but one step at a time :-)
