qemu uses prctl() to set its process title. I bumped up against prctl()'s
16-character limit recently, when adding process title support to

The attached patch overwrites argv instead. Linux seems to maintain the
length of the original args, even when the new args are shorter and
NULL-terminated, so the trailing whitespace in ps(1) output is probably
unavoidable. I've seen the same result with other daemons that overwrite
argv.
