Feature request: reset computation

[client9]

Hello!

I found this via https://github.com/tsenart/vegeta/blob/master/lib/metrics.go

One feature I'd like is to be able to reset the computation back to initial state. I'm capturing performance metrics over a long-lived data stream, and would like to snapshot the behavior every X seconds or so.

I could just make new objects, but it seems it would be nice to re-used the existing ones, especially since you have a pool already.

Or do you think this is a needless optimization and I should just make new objects?

thanks!
