unlink returns EBUSY for remote filesystems explicitely since when we
added MVFS support a couple of weeks back.  If it doesn't work on MVFS,
I don't see any way to change this behaviour.  If you're interested to
get it in, it's you again who will have to debug this in the unlink_nt
functon in syscall.cc.  I still had no luck to get a testversion of MVFS.
