How to 'bypass' the receive timer

Hi Faustin,

it sounds to me that what you want to do is to start a set a timer
in the timer process for each handled message which will be followed by
a second message. Look in stdlib for timer.
timer:send_after(Time,MessageIWillGetBack) for instance. If you get the
expected message you either cancel the time-out or program in a way that
you can ignore it when it eventually arrives.

I guess the reason for going to a special receive statment (having the
time-out) is that you need to handled the second message in a context
dictated by the previous.

You will achieve this by letting the tail-recursive function having the
main receive statment have an argument where such relevant parameters
for that context can be kept.
