From a quick look at Tom's oprofile results, first find out who is
calling into libm and see if you can change the block to stopp calling
libm. For example, calculate sin/cos via a table approximation (I
think GNU Radio already does that).
I think libm already does that, too (table-based SIN/COS), not sure.
