[boost] Status of Boost.Process?

Does anyone know what's the status of Boost.Process? I sent a mail to Julio ten days ago but didn't get any answer. There is some pending work as explained at http://www.netbsd.org/~jmmv/process/boost_process/project_position.html#boos... but it doesn't sound like there is missing a lot. There are various problems in the Windows code though but minor ones (there is for example std::string used everywhere but when compiled as a Unicode program on Windows wide-character API functions are used which doesn't work).
