Can spamd be made to be multi-threaded all the way through?

[Joe Flowers <fl...@social.chass.ncsu.edu>]

Even if spamd is process forking and not spawning worker threads, is it 
possible with the latest production versions of Perl and SA to make it 
muli-threaded all the way through?

When I say "all the way through", I'm wanting to know if, even in a 
threaded implementation, would mutex/semaphore/etc. locks across all 
threads have to be employed at some point?  If locks are required, can 
you give me pointers as to where please?

I hope this question is clear.

Thanks!

Joe
