[libnbd PATCH v3 07/29] lib/utils: add async-signal-safe assert()
...ther (well,
in this case, gather). It's strange that it has taken me one night to
realize this (it occurred to me before falling asleep last night), given
that I heavily used scatter-gather in other, not-so-old, code. (Namely
the edk2 virtiofs driver.)
I'll attempt to replace xwrite() with xwritev().

No, I won't -- writev() is not required to be async-signal-safe, so it's
not good enough for NBD_INTERNAL_FORK_SAFE_ASSERT().
