This adds a small function that concatenates the args (because not
only does the BSD `setproctitle` take a single string, but also the
Linux kernel code that implements `/proc/{pid}/cmdline` won't allow the
"arguments" to extend past their original length unless it's a single
string), and connects it to the fork server.
