    I shall look into profiling etc. and get back to this list with
    precise statistics re: speed vs. (lengh load-history).

I see I did not choose my words clearly.  I am sorry.

The first question is, which *user-level* operations get slow in this
situation?  That you should know from simple observation.

Looking at the code in one of those user-level operations might lead
you pretty directly to the primitive that gets slow.
