      Description

      Running the latest HotJava, I can reliably get the VM to hang here:

          "Clock" (TID:0xed9980d0, sys_thread_t:0xed3f1de0, state:CW) prio=12
      --> "main" (TID:0xed9980a8, sys_thread_t:0x308c0, state:R, intr) prio=7 *current thread*
      Monitor Cache Dump:

      (note the lack of any Java stack in thread "main", indicating that this
      thread has finished executing any HotJava code). The hang happens _well_
      after sunw.hotjava.Main.main() has exited.

      It will spin forever in this thread, sending my load to 1.

      To reproduce on Solaris: Launch HotJava, and go to Edit->Preferences->Applet
      Security. Press reload. I've never had to press reload more than three
      times to get the hang (on my ultra).

      FWIW, I started noticing the problem right after a change to AppletPanel.
      The gist of this change was to make it so that HotJava applets
      (applets loaded via the doc: protocol) all share one P5 thread,
      instead of each getting its own P3 thread.
