I was locking all 848 as an extreme test scenario, to see if I could
reproduce this individual's issue. He was only locking 150 or so

We're rolling out SVN to our whole IT group (about 3 dozen people) of
which maybe a half-dozen have any software development experience and
even fewer have source control experience. As a result, a lot of
people are going to be using "bad" workflows.

A couple of groups are getting the practice of locking plain-text
files, despite my repeatedly telling them that it's not needed. Some
folks are checking out WCs, making a change to a single document, then
deleting the WC after committing - when they need to make another
change, they'll just check out all over again.

There's only so much I can do to "fix" peoples' usage patterns - I'm
just happy that version control is being used at all.
