One job is running that I wish to cancel, and another is in the queue waiting
to start. I cancel the running job, and the next job starts. It fails, moments
later, with an aborted svn update as if I told Hudson to abort the second
build. The initial aborted build was done with a single click and that build
has a grey status orb and logs indicating it was aborted. The abort during the
svn update of the next build causes the second build to fail. (evidenced by the
subversion update stacktrace:
org.tmatesoft.svn.core.SVNCancelException: svn: Operation cancelled
at ... ... ...

Reproducible in 1.200 and 1.210
