--- Comment #2 from Rainer Schuetze <r.sagitario at gmx.de> ---
I've been bothered by the idle CPU time recently too.

Not sure what to do about the additional threads staying around forever, maybe
they could terminate after some time of not running, but that adds considerable
overhead when restarting them.

It seems that the parallel marking has worked out without much troubles (better
than expected). When making it opt-in, only few programs would actually benefit
from that, because people won't bother to change the defaults.
