Override this method in subclasses to support platform-specific
file transmission. It is only called if the application's
return iterable ('self.result') is an instance of
'self.wsgi_file_wrapper'.
This method should return a true value if it was able to actually
transmit the wrapped file-like object using a platform-specific
approach. It should return a false value if normal iteration
should be used instead. An exception can be raised to indicate
that transmission was attempted, but failed.
NOTE: this method should call 'self.send_headers()' if
'self.headers_sent' is false and it is going to attempt direct
transmission of the file.

By default, this just uses the 'error_status', 'error_headers',
and 'error_body' attributes to generate an output page. It can
be overridden in a subclass to dynamically generate diagnostics,
choose an appropriate message for the user's preferred language, etc.
Note, however, that it's not recommended from a security perspective to
spit out diagnostics to any old user; ideally, you should have to do
something special to enable diagnostic output, which is why we don't
include any here!

Usage::
handler = BaseCGIHandler(inp,out,err,env)
handler.run(app)
This handler class is useful for gateway protocols like ReadyExec and
FastCGI, that have usable input/output/error streams and an environment
mapping. It's also the base class for CGIHandler, which just uses
sys.stdin, os.environ, and so on.
The constructor also takes keyword arguments 'multithread' and
'multiprocess' (defaulting to 'True' and 'False' respectively) to control
the configuration sent to the application. It sets 'origin_server' to
False (to enable CGI-like output), and assumes that 'wsgi.run_once' is
False.

Usage::
CGIHandler().run(app)
The difference between this class and BaseCGIHandler is that it always
uses 'wsgi.run_once' of 'True', 'wsgi.multithread' of 'False', and
'wsgi.multiprocess' of 'True'. It does not take any initialization
parameters, but always uses 'sys.stdin', 'os.environ', and friends.
If you need to override any of these parameters, use BaseCGIHandler
instead.
