No, no security issue. The limit to 16 was simply because 16*4 = 64, which kind
of fit a cpu cache line. But the current implement do not make use of this
information often. Merely for the bind system call, which is seldom used (generally
only when a service starts).

So moving to a larger value is not bad. By playing smart, we could do some
as needed allocation and handle any value.
