> In 1.4 when something changed in lib/ext the entire classloader was recreated.   Scans
that were executing when this switch happened would continue to use the old classloader. 

> In the new code scans that started before the switch will start using the new classloader.
 This could lead to a scan loading classes from two different classloaders, which is undesirable.
 Want a scan/compaction/etc to use the same classloader for its lifetime.
