The specific problem was that it was possible to provoke hash collisions by sending carefully crafted input, causing the hash-tables to degrade to linked lists. The small performance penalty of using collision-resistant hashes is certainly worth it in this case.
That has nothing to do with needing exceptions in the control flow path (and the performance penalty for using exceptions in this manner is certainly not small).
