When specified on the command line, all pre-bunch stall indicators will be
ignored. IOs will be replayed without inter-bunch delays.

+ While the \texttt{--no-stalls} option allows the traces to be replayed
+ with no waiting time, this option specifies some acceleration factor
+ to be used. If the value of two is used, then the stall time is
+ divided by half resulting in a reduction of the execution time by
+ this factor. Note that if this number is too high, the results will
+ be equivalent of not having stall.
