question: public synchronized Object co_entry_pause ( int thisCoroutine ) throws java . lang . NoSuchMethodException { if ( ! m_activeIDs . get ( thisCoroutine ) ) throw new java . lang . NoSuchMethodException ( ) ; while ( m_nextCoroutine != thisCoroutine ) { try { wait ( ) ; } catch ( java . lang . InterruptedException e ) { } } return m_yield ; }
target:  In the standard coroutine architecture, coroutines are identified by their method names and are launched and run up to their first yield by simply resuming them; its's presumed that this recognizes the not-already-running case and does the right thing. We seem to need a way to achieve that same threadsafe run-up...  eg, start the coroutine with a wait. %TBD% whether this makes any sense...
