This is necessary for systems that use select as the pollster,
such as Solaris (supported by gccgo). It corresponds to the
bool returned by AddFD. In general it's not clearly defined
what happens when a descriptor used in a select is closed, and
different systems behave differently. Waking up the select
will cause the right thing to happen: the closed descriptor
will be dropped from the next iteration.

to []interface{} to generate []interface{}(nil) rather than
[]interface{}{}. This wasn't caught in the tests because Decode()

arrays. The modification to scanner_test.go quickly triggers
the error:

This is for SPARC64, a 64-bit processor that uses all 64-bits

between a pointer and a type of a different size.

net/http currently assumes that the response to a HEAD request
will always have a Content-Length header. This is incorrect.
RFC2616 says: "The HEAD method is identical to GET except that
the server MUST NOT return a message-body in the response. The
metainformation contained in the HTTP headers in response to a
HEAD request SHOULD be identical to the information sent in
response to a GET request. This method can be used for
obtaining metainformation about the entity implied by the
request without transferring the entity-body itself. This
method is often used for testing hypertext links for validity,
accessibility, and recent modification."
This means that three cases are possible: a Content-Length
header, a Transfer-Encoding header or neither. In the wild the
following sites exhibit these behaviours (curl -I):
HEAD on http://www.google.co.uk/ has Transfer-Encoding: chunked
HEAD on http://www.bbc.co.uk/ has Content-Length: 45247
HEAD on http://edition.cnn.com/ has neither header
This patch does not remove the ErrMissingContentLength error
for compatibility reasons, but it is no longer used.

This function is absolutely critical for clients such as

As with CL 7200046, gri expressed in the doc below [gophers
only] before going on leave that he intended to expose such a
predicate, though his wording suggests as an interface method
of Type rather than a standalone function. (My preference is
for binary methods to be standalone; see "On Binary Methods",
Kim Bruce, 1995). In any case if he wishes to move it that's
easily accommodated by clients.
