There haven't been much news on Boost.Process lately which doesn't mean  
though that nothing is happening. I've been working on a Boost.Asio  
extension which can be used to wait asynchronously for Windows processes -  
see https://github.com/BorisSchaeling/asio. This was already supported by  
Boost.Process 0.4 but the implementation was heavily criticized. The code  
has been moved now to Boost.Asio (or at least I hope it will - I'm in  
contact with Chris :) and provides a new Windows I/O object called  
object_handle. The implementation is now based on the Windows function  
RegisterWaitForSingleObject(). The new I/O object can not only be used to  
wait for processes. It can also be used to wait for events, mutexes,  
semaphores etc. As it's not process-related anymore, it makes sense to  
ship the code with Boost.Asio (where we have already similar Windows I/O  
objects called random_access_handle and stream_handle - object_handle fits  
in nicely).

Once I'm done with this, a major critical point should have been resolved.  
I'll go back then to Boost.Process code and help Jeff to finish  
https://github.com/JeffFlinn/boost-process. I'm not sure how far we are  
there. But as I don't remember any major obstacles, I'm confident that  
there are none. :)
