If we're worried about that, maybe the thin syscall wrapper should be
called linux_getrandom? I think it will be useful to have a thin
syscall wrapper for this, independent of whether we also supply some
hypothetical POSIX-conformant getrandom(), or BSD-compatible
arc4random(), or whatever.

Reserving linux_* for thin wrappers around Linux-specific system calls
also might break the consensus deadlock around the
future-compatibility implications of other such wrappers.
