I has a problem about "-fast-fwd-user-insns N".
In QEMU, if I set checkpoint and also use fast forward command. The 
benchmark will be started 
from checkpoint and then do fast forward for N insts. But according to 
http://marssandbeyond.blogspot.tw/2012/03/fast-forwarding-and-simpoint-
support-in.html  description, "users can use fast-forwarding only once and 
then rely on checkpoint to start simulation at specific RIP everytime", it 
seems that if I set checkpoint and also use fast forward command, MARSS 
will directly be in simulation mode instead of doing fast forward, isn't 
it? How can I do if I want to do fast forward from the check point in the 
benchmark like what I have done in QEMU? Thanks so much for replying in 
advance.
