I checked now why I even had to add -lpthread if it wasn't required in earlier Boost.Process drafts: The new status class uses a worker thread to support asynchronous I/O. So yes, threading=multi is the natural choice. ;) Updated in SVN and in the ZIP file.
The use of a worker thread seems like an unfortunate additional burden. I don't know about the Windows implementation, but on Linux it seems in principle it should be possible to handle it via a SIGCHLD handler.
Callback would need to be async-signal-safe. If a user worries about performance so much, she could set up signal handler itself.
