Some notes:
- The path/ and path\ comes from the "Remote Name"/"Local Name" settings
solution from Issue JENKINS-13264
- We are using Jenkins 1.464 with the 2.4-SNAPSHOT version of the CVS plugin,
but may not have been caused by this specific version
- The arguments setting in the jenkins.xml file currently has -Xms1024m
(anything larger and Jenkins service won't start)
- The CVS module has many legacy projects spread out, and thus, contains more
than 7,000 directories and many more files
- Things had worked with the 1.6 plug-in & CVSNT client, but it also
occasionally timed out getting the changelog, hence our testing of the 2.x
plug-ins
