[srfi-1] lset-difference too slow?

Hey there,

I experienced some problems running the following code.

(require-extension (srfi 1))

(let ((test (time (lset-difference eq?
                                   (iota 10000)
                                   '(-1)))))
  (cdr test))

First, it seems as if srfi-1 seems not to be loaded if followed by
some space character as in
(require-extension (srfi 1 ))

On the other hand the implementation seems to be really slow as I got
results taking round about 300ms while the same code ran in S48 in
nearly no time. Is it possible there is a performance leak in there?
Or is this the price I have to pay intepreting scheme in java?


Thanks and greetings,
Marco.
