Putting them in the unix package means they won't be available for
Windows (where I needed them the most).

For SO_RCVTIMEO and SO_SNDTIMEO, Windows and Unix use different
representations. Windows uses DWORD (unsigned 32-bit) milliseconds,
while Unix uses struct timeval, which has microsecond precision.
