David Xu confirmed for me that pthread_yield() does give some

are two patches for the 1.5 port that is how I suggest the issue be
addressed.
For 7.0 and up default UseThreadPriorities to true and always
use pthread_yield(). For < 7.0 default UseThreadPriorities to
false and conditionally use pthread_yield()/os_sleep(). User's
can toggle UseThreadPriorities with the command line argument
-XX:+UseThreadPriorities
Do we know that 6.x requires the old behaviour? Maybe it can default to
on there too. Otherwise this looks good to my eyeball (but the
DEFAULT_LD_LIBRARY_PATH change looks unrelated)
-#define DEFAULT_LD_LIBRARY_PATH "/usr/lib" /* See ld.so.1(1) */
+#define DEFAULT_LD_LIBRARY_PATH "/usr/lib:/usr/local/lib" /* See
ld.so.1(1)
