[PD] what's the deal with [utime] object?

katja addressed this with Pd Double.  See:http://www.katjaas.nl/doubleprecision/doubleprecision.html
See the "benchmarks" section of that link.

I'm not sure if the output is any different, but it does save the per-sample bounds check and is theoretically faster.

According to katja, that would trigger a zombie apocalypse in external land.  
And the only way to tell the zombies from the survivors would be to... *gulp*...
actually read external library code.
Personally, I'd rather get eaten by a zombie than do that.

actually i strongly disagree: i think it is one of Pd's killer features
to have a single numeric type.

the only problem is that the actually used numeric type (single
precision floating point) is rather limited.
we should have switched to doubles long ago.
