It's not like I wanted to squeeze another microsecond out of the
compile time, but more like trying to bypass some brake, that the
system has slammed full on for no good reason.

Unless, maybe, the system believes that a file write/delete isn't
done until it's physically on the disk and some logs on another...
Kind of like some sync-flag was set. (maybe it even is - hardcoded)

Googling for the symptom I came across suggestions to mount a separate
filesystem over the target folder, and when it's time to clean up, then
just umount,mkfs,mount the partition.  Those people must have been quite
unhappy with their filesystem performance, too, to suggest that.
