SVNKit has a complete API that is similar to SVN, in the sense that it
has many layers. They then provide an implementation of the JavaHL
SVNClientInterface as well, where their implementation, instead of
using JNI, implements it using their own API. Subclipse talks to
SVNKit via the JavaHL interface. So for the most part, Subclipse just
uses the JavaHL interface and we control which implementation is being
used.

SVNKit added an extra boolean named "atomic" to the commit methods for
this feature and Subclipse just had to add some special logic to know
when SVNKit was being used so that we could call this method that was
not part of JavaHL.

The SVNKit code we use is here:

http://svn.svnkit.com/repos/svnkit/trunk/svnkit/src/org/tmatesoft/svn/core/javahl/SVNClientImpl.java

search for "atomicCommit"

Of course you'll then have to trace this into their implementation and
actual API. But that is the starting point.
