What if in a pathological collision (e.g. > 1000 collisions), we increased the size of a dict by a small but random amount? Should be transparent, have neglible speed penalty, maximal reuse of existing code, and should be very difficult to attack since the dictionary would change size in a (near) non-deterministic manner when being attacked (i.e. first attack causes non-deterministic remap, next attack should fail). It should also have near-zero effect on existing tests and frameworks since we would only get the non-deterministic behaviour in pathological cases, which we would presumably need new tests for. Thoughts? Tim Delaney
