Jesse Smith 0b695c7e0b Use readlink() instead of stat() to check processes. This shold avoid
hanging if NFS mounts are not responding.

Default to showing processes in the uninterruptable state (D).
The -z flag no longer affects whether processes in D state are shown.

The -z flag does still toggle whether zombie (Z) processes are shown.
