When separate thread calls flush(), we need to notify Jetty somehow, that it needs to start calling onWritePossible again.

Richard,

have a look at http://git.eclipse.org/c/jetty/org.eclipse.jetty.project.git/tree/jetty-servlets/src/main/java/org/eclipse/jetty/servlets/DataRateLimitedServlet.java?h=jetty-9.1

This is a filter that limits the data rate being sent, so after some writes it decides that it needs to sleep (asynchronously) for a while.

When the scheduler calls back after the pause, we just call onWritePossible from that thread.  But we make sure that onWritePossible always calls isReady() before every write (and does not assume that the first write is OK).

cheers
