You think that a "module-load-list"
(a, a, b) should be the same as (a, b) - i.e. removing duplicates

But there is no good way to decide what to do with (a, b, a),
as (a, b) and (b, a) are really different (order matters);
and therefore we cannot make module loading "idempotent".

And i don't recommend loading modules in vhost configs; you really 
should know what modules are loaded from a look at your main config file.

It is not uncommon that people with debian configs ask in #lighttpd for 
support and don't even know whether they use cgi or fastcgi (or think 
they know and are wrong)...
