Setting the blocking mode of the fd/handles while the other end is already reading/writing may create issues (deadlock in win32 when earlier attempt of this series were using SetNamedPipeHandleState). Let's just do it before spawning the threads to avoid further concurrency issues. Signed-off-by: Marc-Andr=C3=A9 Lureau Reviewed-by: Daniel P.
