Is your SPF library linked against a thread-safe DNS resolver?
 
On FreeBSD ports there are many libspf ports:

# ls -d /usr/ports/mail/libspf*
/usr/ports/mail/libspf          /usr/ports/mail/libspf-alt     
/usr/ports/mail/libspf2         /usr/ports/mail/libspf2-10

and milter-greylist port has options:
 WITH_SENDMAIL_BASE
 WITH_LIBSPF2

with a note:
# If you have a reentrant resolver 
# (starting with RELENG_5_2) you can use SPF

Then I argue that I've a reentrant DNS resolver using FreeBSD 6.x
