One embodiment of the present invention provides a system that facilitates garbage collection (GC) in a memory-management system that supports both mark-sweep (MS) objects and reference-counted (RC) objects, wherein both MS objects and RC objects can be marked and have a reference count. During a marking phase of a GC operation, the system first identifies roots for the GC operation. Next, the system marks referents of the roots. The system then recursively traverses referents of the roots which are MS objects and while doing so, marks referents of the traversed MS objects. During a subsequent sweeping phase of the GC operation, the system reclaims objects that are unmarked and have a zero reference count.
