You may try following snippet as a base for a filter.
(I havn't tried it in a filter chain, so no garantee)

<Filter>
InterruptTimer mTimer =3D new InterruptTimer(5000, 10);
mTimer.start();
try {

  doChain() // Don't have the correct syntax at hand...

} catch (??InterruptedIOException?? ex) {

  // Log what you think to be helpfull

}
mTimer.reset();
</Filter>


public class InterruptTimer extends Thread {
    long oEndTime =3D 0;
    int oSleepTime =3D 10;
    Thread oStartingThread =3D Thread.currentThread();
    Thread oRunningThread =3D null;

    public InterruptTimer(int aLength, int aSleepTime) {
        // Both times are in ms
        oSleepTime =3D aSleepTime;
        oEndTime =3D System.currentTimeMillis() + aLength;
    }
   =20
    public void run() {
        oRunningThread =3D Thread.currentThread();
        // Loop until the end time is reached or reset() was called.
        while (System.currentTimeMillis() < oEndTime) {
            try {=20
                Thread.sleep(oSleepTime);
            } catch (InterruptedIOException ex) {
            }
        }
        if (oEndTime > 0) {
            timeout();
        }
    }
    public void reset() {
        oEndTime =3D 0;
    }

    public void timeout() {
        oStartingThread.interrupt();
    }
}
