OSAL behavior proxy goes to infinite loop in case there is no DAG nor .cc

[Pekka Jääskeläinen]

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<osal version="0.1">

  <operation>
    <name>SHLAND</name>
    <description/>
    <inputs>3</inputs>
    <outputs>1</outputs>
    <in id="1" type="UIntWord"/>
    <in id="2" type="UIntWord"/>
    <in id="3" type="UIntWord"/>
    <out id="4" type="UIntWord"/>
  </operation>

</osal>

This .opp creates an infinite loop in ttasim.

The bug is still there.
