Alright, but would that actually be any better than just doing what
glibc's posix_fallocate() does in the generic case? And, to be honest,
it makes me a bit nervous to seek/write like that because it looks like
the typical "create a hole" setup, which we certainly aren't intending,
yet if the posix_fallocate() call disappeared, or did nothing, or this
code was copied w/o it, or someone didn't understand what it did, we
could end up with that.
Not a fan. :(
Thanks,
