To paraphrase Donald Knuth, "Random numbers should not be generated [using a 
function coded] at random."

It'd be better to fix libc, or considering that has a slow dev cycle and 
platform compatibility limits, use some simple, semi-random, high-performance 
BSD licensed routine from a known-good library.
