The problem is that winsock does not *set* the errno variable in the
case when it's interrupted by an APC. errno is left at 0.
GetLastError() is the win32 replacement for errno. In most cases errno
is set correctly when you use the "unix api functions", but not in this
case (which is arguably a bug, but it's there nevertheless). If you use
"native win32 functions", you get GetLastError() set only.
