i mean we can load image and decompress them in different threads when
we reboot from hibernation.
after i read codes more carefully, that has actually been done by
lzo_decompress_threadfn().

here the problem is we didn't seem to get any faster after applying
your compression patch when doing hibernation on SD/NAND.
we are trying to figure out the reason.
