Module gc_work 

Structs

Prepare

The global GC Preparation Work This work packet invokes prepare() for the plan (which will invoke prepare() for each space), and pushes work packets for preparing mutators and collectors. We should only have one such work packet per GC, before any actual GC work starts. We assume this work packet is the only running work packet that accesses plan, and there should be no other concurrent work packet that accesses plan (read or write). Otherwise, there may be a race condition.

PrepareCollector

The collector GC Preparation Work

PrepareMutator

The mutator GC Preparation Work

Release

The global GC release Work This work packet invokes release() for the plan (which will invoke release() for each space), and pushes work packets for releasing mutators and collectors. We should only have one such work packet per GC, after all actual GC work ends. We assume this work packet is the only running work packet that accesses plan, and there should be no other concurrent work packet that accesses plan (read or write). Otherwise, there may be a race condition.
