This is not desirable since it moves the cost from
one-per-context-switch to once-per-return-to-userland. That said,

There are several design issues that prevent us from implementing USER_LDT on
amd64 easily. I don't quite know how to fix them yet; I'm just posting here some
thoughts in case someone is interested or finds an easy way of fixing all of
that.
Let's consider a 32bit lwp, from netbsd32 for example,
Michael, Martin, thank you for letting me know about wedge(4).
It is exactly what I need! It is more portable than my patch.
I withdraw the patch and the PR.
Thanks,

Thanks for your advice, and I will have a try :)

There is no special wedge configuration on the disk. Wedges are
generated from labels. There is code to handle GPT, MBR and BSD disklabel,
the latter is not configured in
