Existing problem with wait states in Sprinter is big performance pressure for the Accelerator related tasks.
This commit delivers trade-off for both preciseness and performance:

  • Non batched (one step) operations are processed in CPU's running window using icount adjustment.
  • Batched keep using own timer and put CPU in "real" WAIT state, but merging all iteration in single window.
