Perhaps I need to re-review the analysis of CLR-1990*, because they clearly state on page 223:
The worst-case running time for insertion is O(1). For searching, the worst-case running time is proportional to the length of the list: we shall analyze this more closely below. Deletion of an element x can be accomplished in O(1) time if the lists are doubly linked.

Note, I wasn't referring to perl's hashes in particular, just hashes in general.
