modify send() to block until entire buffer is sent

Ok so I couldn't wait until the weekend :-).

It looks like on Windows, for non-overlapped non-blocking stream sockets,
send()/WSASend[To]() block until the entire buffer is sent, while on Linux, it
tries to return as soon as any bytes have been sent. Code written *the proper
way* will work on any operating system, while some heathens write code that
doesn't fully check the return value of send() and resends the remaining bytes,
so outside Windows, every send() can skip some bytes, leading to problems like
you see here. (What an evil ploy - by modifying the semantics of send(), code
written for other operating systems can be ported easily to Windows, but code
written for Windows with those assumptions will need to be rewritten to work
properly anywhere else).

My patch modifies WSASendTo to try send everything, like Windows does. Please
try it and let me know whether it works.

winsock-patched-trace.tar.bz2

Sorry to report the patch from comment #7 made no difference from a usage
standpoint, the behavior is identical to before.

I just tested it, and if you reduce the lo network interface's MTU to 1500
(ifconfig lo mtu 1500), it does hang even when accessing pages on localhost.
