WebGarbage collection (GC) needs to occur when there are known, stable pointers to the set of 'root objects' that can be traversed. At certain points in the program, this condition is satisfied. These points are called safe points, and the program can be stopped so GC can occur safely. For GHC, allocating any amount of memory is a safe point. WebHaskell/GHC garbage collection.
