That's how it _should_ work.
I made up a little test case (see the attached Makefile), and that test
fails sometimes when I interrupt it by pressing Ctrl+C.
$ ktrace -i make -r -j20 # press Ctrl+C in the middle
$ make -r clean && ls -l
At this point, there may be one or more files named 'target-*' left that
are smaller than the expected 14 bytes.
I got the ktrace log from the above command and will further analyze it.
