Do you mean literally calling "sleep()"? You should never, ever call Thread.sleep() inside an Actor, and you shouldn't need to -- at worst, you have the Actor use become() and stash() to store up messages until you get the response you need; once you have all the needed information, you process that, unstash() and become() back to the normal state.
Basically, blocking is always a bad idea inside Actors (for exactly the reasons you suggest), and except for when interfacing to external libraries it is basically never necessary. Always figure that there is a non-blocking way to deal with the problem. stash() and become() are usually your friend in such situations...
