Won't this fail in 6000 years time... Perhaps not an issue, but
maximum duration is gettime_ns() + INT64_MAX (and these tests serve as
part of the ABI guide / documentation as well as checking the contract).
We don't have an encoding for an infinite wait, I guess several millennia
will just have to do.
