Or more concisely using just coreutils logic:

sleep $(seq .1 .1 4 | shuf | head -n1)

This still has the quantization effects which I'm trying to avoid. Jim's perl suggestion would work well to ensure an even spread over the window of time.

$ perl -e 'sleep rand 4'

is probably the cleanest / most efficient way to do this with existing tools.
