I'm not sure why the processes are not migrating (getting EBUSY but not = sure why). I'll look into it later today.

I could fix this because=20 /dev/zero is a special case, but I have more important bugs to fix at=20 this moment. Killian, if you would, please open a bug report on=20 Sourceforge so we don't forget about it.

Well, indeed, as I might have said in a previous mail, I can now migrate=20 individual apache threads, so perhaps newer apache versions are not mapping= =20 devices anymore. It would probably be useful to open a bug only if other=20 users still experience the I-can't-migrate-apache-threads symptom.
