DbgView uses (near) 100% CPU

1. Simply start DebugView v4.90. (It used to be v4.81 in 2017.)
Note: On first run, there is the additional "Agree to licence" dialog.

Virtual PC 2004 SP1 (5.3.582.27)
WXP
No issue (Cpu = 0 %).

Virtual PC 2004 SP1 (5.3.582.27)
bootcdregtest-75167
Cpu = 50-60 %, (Program state = Running <-> (random) Not Responding).
Task Manager itself already uses Cpu = 15-30 %. (TM + DV = (near) 100 %.)
Fwiw, this already happens with bootcdregtest-75044.

A busy wait/loop somewhere in ROS (Debug)?

DbgView is the recommended tool to work with AHK Tests.
It obviously can't be used as is.
Note: Workaround for this use case is to read/search ROS (Debug) debug.log. (Painful.)
