>Subject: [PATCH] Do not show tasks when no selector option is present.
>
>Normally tasks share file descriptors so the information is quite
>redundant, and when there are processes with both many files and many
>threads running a simple lsof -nP takes orders of magnitude more
>time. If wanted information for tasks can still be listed by using the
>-K option.
