i think what markus meant is that he had 100000 entries in a who object,
not rules. That is (sadly) rather realistic and we encounter it often with users/customers.
(even if we don't recommend it)

i think it's easier than you think to blow up the filter memory usage, we're already
100 MiB up from the initial assumption without adding any new rules/objects by default.
(e.g. a new spamassassin update can increase that probably quite easily)

while 300 might be excessive, on our machines we easily observe 230 MiB per worker
so that could be a fine value (like Markus suggested)
