[Coin-symphony] Recording feasible solutions

Hi all
I am researching the SYMPHONY framework as a possible solution for a
system that I'm working on. Everything seems to work quite nicely so
far, though with a couple of quirks.
In this system, we are not really too concerned with finding _the_
optimal solution; rather, we are searching for many near-optimal but
diverse solutions. Of course, if we happen to find a provably-optimal
solution, we're happy too, but this generally takes too long for our
application. As such, we need to record feasible solutions as they
are found.
I've tried using user_send_feasible_solution, but this function never
gets called (and the documentation confirms that it will only get
called if running the LP module in a separate process, which I don't
want to do at the moment). I could use user_is_feasible, but it
doesn't seem quite the right place.
Am I missing something? Is there another event that is called when a
feasible solution is found?
Thanks in advance,
David
