Public bug reported:
I've modified qemu to overwrite its arguments to set the process title,
since its current prctl() method has a 16-character limit.
I posted the original patch to qemu-devel, made the changes others
suggested, then re-posted to qemu-devel. I flailed around a bit with the
patch

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.
