......................................................................


Patch Set 2:

:(

Ah, nice.

 > I believe there is also a newer version of pprof implemented in go,

That's right. Go has a nice package https://golang.org/pkg/net/http/pprof/ that 
basically gives a lot of this profiling kind of stuff exposed over an http 
interface for free just by importing it, plus a pprof tool built into the go 
toolchain for processing the result.
