In practice, though, there has been a more liberal use of this /u flag
because putting it on several writes to the same memory location doesn't
seem to cause any problem as long as every write to the said location
carries the /u flag (because the memory writes then conflict).
No, I don't think that's right. I'm pretty sure that there is some
code someplace that will fail if there are two writes to the same /u location
and I thought we added code to prevent any such.
