sorting associative array's keys by values

[maarten van damme]

Ah, wait a second. After playing a bit with the try catches and
actually writing some proper debug output I found out the problem was
with https://github.com/Bystroushaak/DHTTPClient/blob/master/dhttpclient.d.
It doesn't allways download the complete webpage.

I should've written better tests I guess...
Thank you for your time.
