You certainly shouldn't use its output directly, but as I understand it, if you were to push the output into the OS's entropy pool, it will get automatically whitened, combined with other entropy, and fed into something like Yarrow. The end result should almost certainly be at least as secure as the default entropy sources of keyboard timing, hard drive read/write latency, etc. If you're using a lot of random numbers, then /dev/urandom would become far more secure, and /dev/random would become far faster, since the entropy pool wouldn't drain as quickly.
