PmWiki doesn't have edit locking, and doesn't need it.  If
two or more people attempt to edit the same page at the same
time, then when each person saves PmWiki will merge the
authors' changes together (and mark any conflicting 
edits so they can be resolved).

There are a lot of reasons why "page locking" doesn't work
in this context; the biggest being the problem of knowing 
what to do if someone requests editing a page but doesn't 
save it (i.e., jumps to another page or closes the browser)
or otherwise doesn't release the lock.  So PmWiki just
avoids the issue altogether by merging multiple edits

(See http://pmichaud.com/pipermail/pmwiki-users_pmichaud.com/2003-August/001125.html for a fuller description of the problem.)

However, I do need to write a page to document and describe
the simultaneous edit handling features of PmWiki.  :-)
