I'm not sure this URL actually points to a relevant issue ?

I already have the implementation which eliminates the wildcard if we
care about this. It was part of a previous hazptr series version.

Do you want me to resurrect it on top of the current series ?
This depends on:

- ptr_eq(),
- then use ptr_eq() to compare the loaded pointer (pre mb)
   with the re-loaded pointer (post-mb).
