recv and see if it is WSAENOTSOCK. However the recv may block
after the server process died and thus the destroy_reader will
hang. Another option is to use getsockopt to test whether it is
a socket. The bug here is that once a socket with a certain
values has been opened, closed and later a CreatePipe returned
the same value (i.e. handle), getsockopt still believes it is a
socket. What we do now is to use a combination of GetFileType
and GetNamedPipeInfo. The specs say that the latter may be used
on anonymous pipes as well. Note that there are claims that
since winsocket version 2 ReadFile may be used on a socket but
only if it is supported by the service provider. Tests on a
stock XP using a local TCP socket show that it does not work. */
