Re[2]: [Gc] Calling ‘GC_INIT’ from a secondary thread

NP, I think. Just prepare a patch.

There is only one problem: Solaris expects GC_INIT to be called from the main thread due to:

  /* These variables are used to cache ss_sp value for the primordial   */
  /* thread (it's better not to call thr_stksegment() twice for this    */
  /* thread - see JDK bug #4352906).                                    */

Is there a way to find out whether this is a primordial thread on not on Solaris? if yes then it would be easy to fix the problem on Solaris as well.
(I don't see any other multi-threaded platform that prevents calling GC_INIT from non-primordial threads.)
