New Revision: 222532
URL: http://svn.freebsd.org/changeset/base/222532
Log:
- Document the -H option and 'H' key alongside other options and keys
rather than at the bottom of the manpage.
- Remove an obsolete comment about SWAIT being a stale state. It was
resurrected for a different purpose in FreeBSD 5 to mark idle ithreads.
- Add a comment documenting that the SLEEP and LOCK states typically
display the name of the event being waited on with lock names being
prefixed with an asterisk and sleep event names not having a prefix.
