Hello,

This patch changes:

-      /* We can only poke around if there actually is a child process.
-         If there is no child process alive, postpone the steps below
-         until one has been created.  */
-      if (proc_handle.pid != 0)
-       {
-         enable_thread_event_reporting ();
-         thread_db_find_new_threads ();
-       }
+      enable_thread_event_reporting ();
+      thread_db_find_new_threads ();

this code is only executed when there is a child process so the guard 
isn't needed.    Tested on GNU/Linux, no change in test results.

ok?
Andrew
