I think the problem is introduced by following change.

+Sun Nov 28 22:13:39 2010  Koichi Sasada  <ko1@atdot.net>
+
+       * thread_pthread.c (NATIVE_MUTEX_LOCK_DEBUG): move and use it.
+
+       * ChangeLog: fix my timezone.
+
+Mon Nov 28 21:58:58 2010  Koichi Sasada  <ko1@atdot.net>
+
+       * thread_pthread.c: remove pthread_atfork().
+
+Mon Nov 28 21:54:22 2010  Koichi Sasada  <ko1@atdot.net>
+
+       * thread_pthread.c (native_cond_*): Check return code.
+         (Some OSs except Linux return error code).
+

After the change, TestPTY#test_getpty_nonexistent stucks frequently
(not always).
