BOREALIS_NAMESPACE_BEGIN

This box is a waitfor modification for linear road. One stream buffers tuples. The other stream is like a "control stream" , providing a new value for some key "n" (int). Buffered tuples are let through if one of their fields is <= n. Specifically - the control stream updates the "key field value" (n) This box always lets through tuples that have key field <= n At startup, without any control tuples, all data is buffered Data comes from input stream 0 "Control" comes from input stream 1
