1. Are you saying you expect to use it rwhois so much and so often that
    one thread is just not enough? For what?????

2. You can always use  whois client library - after all rwhois is just
    normal whois with additional processing to understand record format,
    and relation of one type of record to another and find what the db
    schema is. But in reality normal whois client will give you the
    expected output in regular text form that you can alredy use
    depending on what you need it for.

    For example if you do 'whois -h completewhois.com idnic.net.id'
    (see below) you'd think we're doing real rwhois processing, but in
    reality its normal whois with some simple regex code to get rid of
    rwhois class names (i.e. "domain:") for nicer user output.

While strict rwhois processing would have given:

Class-Name                    domain
