Benchmark: VW has a problem here, too (maybe not a good excuse...). It has
been pumping away at your sample code for a couple of minutes now. The
SmallInteger version takes 37ms on my PII/400 with VW, the LargeInteger
version a couple of minutes (still holding on).

32 bits is 4billion objects, or are you using a lot of bits at the front to
get it down to 32m?
I'm happy with 32m as well (although you always have the risk that you maybe
don't have 32m at a certain point of time, but surely that you cycle through
all the 32m oids in a reasonable amount of time.
Visual is still pumping. Instead of boring you with the Usenet equivalent of
Muzak while waiting for the answer, I'm going to fetch a drink...
VW takes 622,918 ms on my box. 10 minutes is better than 4 hours, but still
