I noticed this post that was also related to report serialization and jaxb: https://developers.google.com/adwords/api/community/?place=msg%2Fadwords-api%2F2h_hhyThed0%2FN94XKOfR2GoJ
I made my own version of the serializer for a ReportDefinition object, that creates a single JaxBContext object and reuses it instead of making a new one each time. According to some web searching that I did, the JaxBContext is threadsafe so this should be fine, and in fact the recommended approach is to use just one JaxBContext. This change made a significant reduction in my CPU utilization, in addition to the permgen memory issues that Eli mentions in the post above.
