Hi All,
Attached is a simple patch adding some logging before and after the
garbage collector is invoked in the MRUMemoryStore. Hopefully this can
give us some indication as to how much has been freed, and what is
available.
Diff is against the cocoon_20_branch ? (is this ok, or should it
really be against trunk ?)
Cheers,
Marcus
