I'd like to see the possibility to send signals to the child process too.
posix_child pchild( child); pchild.signal_sigstop(); pchild.signal_sigcontinue(); etc.
Sending signals to the child process is quite trivial: simply invoke the POSIX kill function with the pid of the child. You don't even have to worry about looping to handle EINTR. Potentially boost.process could provide an interface for this, but as it is specific to POSIX, and it is basically impossible to have a simpler interface than already provided by POSIX, it seems rather pointless. In contrast, handling signals, and SIGCHLD in particular, is quite complicated, and therefore it would be quite useful for Boost.Process to provide proper handling, as already discussed.
