Please reread my message that Johann was replying to:

Caching the repeated lookups only works when Spamassassin is working.
When Spamassassin fails (such as due to a timeout), there's no result to
cache, so each invocation in the ACL re-runs it. And a message that
fails with a spamassassin timeout is exactly the worst possible time to
be rerunning it 5 times for your CPU and disk.
