Yes, and for the immediate case you can use Future.successful.

Hi John,

I think it is easier to use the built-in throttle:
 - set the capacity to zero
 - set the token rate to 1/second
 - use an explicit cost function, setting the cost of non-empty sequences
to zero, and the cost of empty-ones to ten.

-Endre

I came up with this code:

http://pastebin.com/LNTCvebe

But beware  until now I have only be using akka with java. It is my first 
try on using scala!

As a side note : I could not figure out how to match an non-empty list in 
receive?

Many Greetings

Something very simple which come to my mind is  to mapAsync to the ask 
pattern and then do a "schedule of 10 secs" if the element is an empty list.
