Total number of nanoseconds wasted in closures. Wasted time is a difference between wall time and cpu time used to execute a closure. It is called wasted, because high value of it means, closure was sitting blocked (for example waiting on Mutex, IO, Sleep or doing busy wait) or not scheduled by kernel, due to the process being over CPU limits, or process is trying to run too many threads at the same time, than there is available CPU cores in the system.
