[Toybox] Still poking at shell corner cases...

[enh]

works for me as root. i think your copy & paste got mangled somewhere.
strace says the shell is opening files in /data/local/tmp/:

newfstatat(AT_FDCWD, "/data/local/tmp", {st_mode=S_IFDIR|0771,
st_size=20480, ...}, 0) = 0
openat(AT_FDCWD, "/data/local/tmp/shcj1bft.tmp",
O_RDWR|O_CREAT|O_EXCL, 0600) = 3
openat(AT_FDCWD, "/data/local/tmp/shcj1bft.tmp", O_RDONLY) = 4
write(3, "hello\ntwo\n", 10)            = 10
close(3)                                = 0
fcntl(0, F_DUPFD, 10)                   = 11
fcntl(11, F_SETFD, FD_CLOEXEC)          = 0
dup3(4, 0, 0)                           = 0
close(4)                                = 0
newfstatat(AT_FDCWD, "/data/local/tmp", {st_mode=S_IFDIR|0771,
st_size=20480, ...}, 0) = 0
openat(AT_FDCWD, "/data/local/tmp/shyryaav.tmp",
O_RDWR|O_CREAT|O_EXCL, 0600) = 3
openat(AT_FDCWD, "/data/local/tmp/shyryaav.tmp", O_RDONLY) = 4
write(3, "and\n", 4)                    = 4
close(3)                                = 0
dup3(4, 0, 0)                           = 0
close(4)                                = 0
