Chapter 41 of the manual:
http://www.exim.org/exim-html-current/doc/html/spec_html/ch41.html#SECTscanspamass
includes the statement:
The spam condition caches its results. If you call it again with the
same user name, it does not scan again, but rather returns the same
values as before.
So your ACL fragment below should be efficient; spamassassin should
only be called once as you're always using the "nobody" username.
