Claim 6:
7. The method of claim 1, wherein identifying which of the plurality of shared read-only objects can be garbage collected comprises, for each of one or more of the plurality of shared read-only objects:
when the first data structure indicates that the shared read-only object is readable, which is based at least in part on the “deleted at” value stored in the first data structure, retaining the shared read-only object;
otherwise, when the reference count is not zero for the shared read-only object, retaining the shared read-only object;
otherwise, when any secondary node is reading the shared read-only object, retaining the shared read-only object;
otherwise, when the respective second global commit id from the second data structure for any secondary node is less than the “deleted at” value for the shared read-only object, retaining the shared read-only object; and
otherwise, identifying the shared read-only object for garbage collection.
