Also if order 1 allocs were a significant problem on i386 we must have had lots of reports of EAGAIN on fork/clone with !4k stack kernels. I'm not aware of an significant number of such reports (there were a few occasionally, but that is probably normal and unavoidable and can be caused by other things too like simply running out of lowmem)
