Yes, the syscall sequences in cp are different than those in tar, as to
whether the utility cares whether the inode is changing in the middle of
the copy.  Personally, I think coreutils' behavior is more correct in the
face of accurate inodes, because it detects if some other process is
modifying the filesystem in parallel with you; but as you found out can be
annoying when dealing with a filesystem that does not have accurate inodes
when no other external modifications are happening.  It comes to a choice
of which battle do you want to fight.
