Doh, yes that would have been worth mentioning! :)

I'll update it before I commit it.

Yes everything passes, thanks very much for the tests BTW.

And for the record I've tested on: ppc64, ppc64 (compat), ppc64le,
ppc, ppc64e and ppc64e (compat).

Yeah I noticed that and though "oh jeez not syscall_restart", but it seems to
pass, so I guess we behave in a standard fasion for once. I'll have a closer
