I've checked in a simple main program netxx_pipe_stdio_main that uses
StdioStream and StdioProbe; it is used in the netxx_pipe.cc unit test
pipe:spawn_stdio.

./unit_tester.exe pipe:spawn_stdio gives on Win32:

C:\Gnu\monotone.experimental.win32_pipes\unit_tester.exe: Subprocess command 
line: 'netxx_pipe_stdio_main '
exception: select(2): An operation was attempted on something that is not a 
socket. (10038)

./unit_tester.exe pipe:spawn_cat passes, so it seems one side of the
interface is working.


On Unix, ./unit_tester.exe pipe:spawn_stdio passes.
