Thank you to Andrew for developing and supporting Bleachbit (and to everyone who helps); it's very generous of you. I ran into a problem that I hope someone can help with.
Wiping a large amount of free space on an external hard drive, Windows' System process (one thread in particular, per a process manager) consumes an increasing amount of CPU over time. It starts under 10%, but in one test was using over 20% within ~45 min. In another test, after around 9 hours, System was using over ~70% and Bleachbit's estimated completion time had more than doubled.
