While most people are probably aware of the effect of dns lookups, it doesn't hurt to have a paragraph in the README.md. For example something like the following.

DNS Lookup
If you use a non-ip as the statsd host, be aware that each UDP packet sent will trigger a DNS lookup. This breaks the fire-and-forget functionality since the udp packet cannot be sent until the DNS network round trip has completed. Popular methods around this issue are hardcoded /etc/hosts files and the use of software such as nscd.
