A quick overview of what svn-lock does can be found in the below quote
The poll will last for 7 days.
Any developer can 'get-a-lock' on a file. Having this lock means only that developer can commit to that file*. A locked file cannot be modified, deleted or renamed in the repository by anyone else.
To set a lock on a file, you lock it as per your client syntax and set the subversion property svn:needs-lock. When this property is set on a file, a checked out or updated file is made read only locally. (except for the person who holds the lock*). This acts as a warning that the file should not be modified. Users of Tortoise will also have a graphical overlay stating a file is locked.
Locks can be removed by any developer in a process called breaking-the-lock. (ownership of the lock can also be taken known as stealing-the-lock, although that's not important for us). The ability to Break the lock ensures that no one developer has control over the lock. Anyone can remove a lock at any time.
Users and developers alike will not notice a lock unless they try to modify locked code, so it would in no way inhibit general usage.
*a user named 'audit' can be set up to do the initial locking of the files
