         When the <b>Equinox OSGi Framework</b> is launched the installed bundles are activated

         activated first. Bundles within the same start-level are activated sequentially from
         a single thread.
         <p>
         A new configuration option <code>equinox.start.level.thread.count</code> has been added
         that enables the framework to start bundles within the same start-level in parallel. The
         default value is <code>1</code> which keeps the previous behavior of activating bundles from a
         single thread. Setting the value to <code>0</code> enables parallel activation using a
         thread count equal to <code>Runtime.getRuntime().availableProcessors()</code>. Setting the
         value to a number greater than <code>1</code> will use the specified number as the thread
         count for parallel bundle activation.
         </p>
         <p>The default is <code>1</code> because of the risk of possible deadlock when
         activating bundles in parallel.  Extensive testing must be done on the set of bundle
         installed in the framework before considering enabling this option in a product.</p>
