POE Component for domain name resolution

 POE::Component::Resolver is a Perl module that provides nonblocking domain
 name resolution by using Socket::GetAddrInfo's getaddrinfo() function in
 subprocesses where they are permitted to block indefinitely.
 .
 By default, it will use a maximum of eight subprocesses and prefer address
 families in whatever order Socket::GetAddrInfo returns them. These defaults
 can be overridden with constructor parameters.
