+* segfault with ./loba cluster1000.xml -N64 -a fairstrategy
+
+ this is a deadlock occuring when:
+ - a process is in the finalize stage;
+ - all processes but one are blocked on receive;
+ - the process that is still running owns all the remaining load,
+ and sends it all to the finalizing process, and then goes in
+ blocking receive.
+ The finalizing process receives the load, and blocks again,
+ waiting for a close message.
+ All processes are then blocked, and non-one is able to see that
+ there is no more load in the system!
+
* verify bookkeeping version.
-* add minimum (sleep) time between 2 lb iterations ?
+* add several metrics
+ - flops (total, avg, stddev)
+ - message exchanges (number, volume)
* add options -j/-J : minimum number of iterations ?
