OutOfMemoryError when recording changes

We were attempting builds following the introduction of a large number of changes into the repository via a cvsimport operation. (Running 'git whatchanged' from the command line yields 100K+ lines of information.) Following the message "Recording changes in branch..." the plugin invokes "git whatchanged", and the process subsequently runs out of Java heap space, reporting OutOfMemoryError. Allocating additional heap space has helped in some circumstances.
