Abstract
The present invention provides a system that facilitates performing concurrent garbage collection. During operation, the system executes a first mutator thread. While executing the first mutator thread, the system performs a garbage-collection operation using a garbage-collector thread. Performing the garbage-collection operation involves: discovering a live object in a from-space, which is being collected; creating a copy of the live object to a to-space, where live objects are copied to during garbage collection; and replacing the live object in the from-space with a forwarding pointer which points to a location of the copy of the live object in the to-space.
