Subversion has many other benefits over CVS including atomic commits
which link related file chages together, local pristine copies which
makes diffing your local changes very fast, good network scalability,
etc.

Soon, soon. Subversion 1.2 is due to enter it's release phase next week
and that will take about another month to complete. The new version
implements optional file locking, which means you can mark a file as
requiring a lock. In order to commit changes you have to be in
possession of the lock token.
However, the big question is why your superiors want this. For binary
files where merging of changes is not possible then the answer is
obvious. But for text files (source code, html, etc.) the standard
methods work better. The subversion book describes the different ways of
working very well, including the problems associated with locking
systems. Both subversion and TSVN are hosted on subversion repositories
without locking. There are only a few active committers on TSVN, but
subversion has a considerable number.
