I certainly wouldn't call it a feature.  As others have
noted, it is a known shortcoming in FreeBSD, and fixing
it is non-trivial.

Always remember to umount devices before removing them.
Using amd(8) with a short timeout can help somewhat.

Best regards

I suggested holding a "Python Object Oriented Programming Seminar",
but the acronym was unpopular.
