Yes, agreed, that's something to be concerned about.
It wasn't the specific functions that I mean though, just anything which
has the kind of "randomness" that rand() produces (which isn't much, but
is plenty good enough for the communications between a stub resolver and
its cache (aka back end resolver)) in almost any situation - and in the
cases where it isn't, something like TSIG is required, not a better random
