Multithreaded HTTP Download

[Mike McKee via Digitalmars-d-learn]

Hey guys, as it turns out, someone on stackoverflow.com pointed 
out in a Perl version of this question that the Bash example that 
was given is really buggy and doesn't make sense. They say that 
trying to download a single file using two socket handles will 
not speed up the download. So, this may or may not be possible. 
Your thoughts?
