Thanks

I have tried the fix and it stops wget from stalling. However, it is very slow.
Retrieving a small file, which should be completed within a fraction of a
second sometimes takes several seconds.

Basically, I think you need to arrange the code in such a way that you are sure
that the fread() buffer is empty before you call poll().

I have attached a Wireshark trace that demonstrates the problem.
