   PTAL. There is no lock contention in `SetPTransformState` now because we are 
using atomic.Value for updating the state and pid. However, this has been 
compensated in the allocs/op. It changed from 0 to 2 allocs/op. 
   
   There is a lock contention in case of `s.Sample` . If we can use normal 
`int` for storing the time instead of `time.Duration` then we can get rid of 
that lock as well.
