Description

As RevisionGCMBean.startRevisionGC() can be used to manually invoke a gc cycle, there is the danger of running into a SNFE when gc is run multiple times in quick succession (due to the retention time being based on number of generations). We should come up with a mechanism to prevent this scenario.
