XZ Embedded saves only code size. If the file was compressed with
settings that make the decompressor require e.g. 65 MiB RAM (xz -9),
using XZ Embedded won't help you.
XZ Embedded is also very limited. It cannot decompress all .xz files. It
should still be quite useful, since on some architectures it can
compress the kernel image better than the current LZMA support in the
kernel, and the API should be nice to use e.g. by Squashfs.
