* it might be a bit confusing as it shows number of threads before making
  the decision to start more tasks and also it can show only a few tasks
  running, but not because of pressure when there just aren't many tasks
  left or wait for their dependencies to be finished first

* example output:
  NOTE: Pressure status changed to CPU: True, IO: None, Mem: None (CPU: 297589.5/200000.0, IO: 5522.2/None, Mem: 779.2/None) - using 7/8 bitbake threads
  NOTE: Pressure status changed to CPU: False, IO: None, Mem: None (CPU: 196381.2/200000.0, IO: 2667.9/None, Mem: 556.2/None) - using 2/8 bitbake threads
