#946: Async scriptland functions stack explosion

---------------------+------------------------
 The example directly from the CHANGES file results in a stack explosion.
 I was doing some work with callbacks and realized that I needed a
 continuation but this is the only mechanism currently available in
 scriptland for doing continuations (just to point out that this is
 actually blocking me right now).

 {{{
       global X: table[string] of count;

       function a() : count
             {
             # This delays until condition becomes true.
             return when ( "a" in X )
                   {
                   return X["a"];
                   }
             timeout 5 min
                   {
                   return 0;
                   }
             }

       event bro_init()
             {
             # Installs a trigger which fires if a() returns 42.
             when ( a() == 42 ) { print "Yippie!"; }

             X["a"] = 42;
             }
 }}}
