(feature request) pprof wall time profiling

[Patrick Lee]

(tl;dr I want google3's wallz profiling)

Hey guys,

While cpu profiling is great for debugging where we spend our cpu, it's terrible for debugging latency issues because I/O, time.Sleep, blocking on channel for items, etc. are not counted against cpu time.  Can someone extend golang's pprof to also support wall time profiling? 

Thanks,

Patrick
