Actually, it can crash the operating system if the kernel happens to try to
write to swap space or needs to write buffers to disk, potentially leaving
a corrupted file-system.  Might not happen as much now with ext3 and ext4,
but still...  If you are going to try that, then a) don't use swap and b)
run 'sync;sync' before the hard drives are spun down.
