Mike Ash 81a6a7166c [RemoteMirror] Put a limit on pointer-chasing loops to avoid infinite loops. Report Slab's Next pointer as a separate chunk. ...

When iterating over linked lists in the target process, bugs or corrupt data might cause us to enter an infinite loop. Limit these loops to a fixed number of iterations so that we fail more gracefully. These limits should be set to a level that no healthy program will approach.

Report Slab's Next pointer as a separate chunk in asyncTaskSlabAllocations. This lets tools see it as a pointer and see the connection to the next slab.
