Perhaps "leaks" is a bad word, since it implies "unreferenced allocations". Languages that rely on GC'ing allocations reference the allocations in the allocator. They are only unreferenced as far as the program is concerned. >From the perspective of a program that believes it is running in its own virtual machine, however, there is very little difference between memory referenced by an allocator but not by me and memory that has leaked. In either case, until the GC runs, there is a program-observable leak. Terry Lambert terry@lambert.org --- Any opinions in this posting are my own and not those of my present or previous employers.
