@tstuefe whether other kinds of thread iterators have potential issues with the state of the threads they may observe is not relevant to the question of whether the proposed check goes in the iteration loop or the HANDLE_THREAD macro - we don't process any GC threads with HANDLE_THREAD. The JavaThread iterator can return a thread that has not yet set its stack so the code using the iterator needs to deal with that if it might be an issue.
