The ups and downs of strlcpy()

Yeah, true. But if ptrace() was something everyone had to use, a replacement would have been merged by now, because ptrace() is just so odious in so very many ways. (Though the improvements in recent kernels have been substantial, and in maybe as few as five to ten years I'll be able to rely on them enough to actually use them in real software, which these days means "meant to be portable between Linux distros, including the dinosaur-era RHELs too many people insist on running their bleeding-edge software on". sigh.)
