--- Comment #3 from Vladimir Panteleev <dlang-bugzilla at thecybershadow.net> ---
std.socket is a rather thin wrapper around the platform's C socket APIs, so
it's very likely that problems not specific to the wrapper are going to
manifest there as well.

If you want to get to the bottom of this, I'd suggest installing a free version
of Visual Studio, translating the program to C, and seeing if it behaves
differently.
