Hi, Fan Bin, Weldon's story is great! But I wonder.. do you need to suspend a thread from within itself or from another thread? For the first case you can do almost the same thing as insertion of Object.wait() does. Suspending from another thread happens just like during GC enumeration from Weldon's message (a flag in 'thread local storage' is checked via a special 'VM helper' call inserted by JIT). Call for more details if you need to. -- Egor Pasko, Intel Managed Runtime Division --------------------------------------------------------------------- Terms of use : http://incubator.apache.org/harmony/mailing.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
