Something that struck me earlier this week was when profiling certain workloads, I'd really like a flame graph that included wall time waiting on IO, be it a database call, filesystem or other RPC.
For example, our integration test suite on a particular service has become quite slow, but it's not particularly clear where the time is going. I suspect a decent amount of time is being spent talking to postgres, but I'd like a low touch way to profile this
