That's a possibile approach for cases in which many synchronized signals
need decoding.
My idea (which should be useful even when there's only one signal to
decode) is simply to parallelize the "ntrials" loop starting around line
~147 of sfrsd. Each thread would begin with its own random seed and
have its own local variables for era_pos, workdat, etc. Each thread
would keep track of its own nhard_min, nsoft_min, etc. When any one of
the threads produces a decode, it would terminate the others and
continue as a normal single thread.
