All you can create as thread within snort are the output-plugins.
So they would work parallel. But if one plugin is blocked the
whole snort process is blocked.

I guess you think of something similar in design like FLoP where
you want to put the detection engine in one thread and the output
in another thread. This may work but would require a lot of work
to be done. 

But what is wrong with the existing solutions like barnyard, mudpit,

I think all the existing solutions are better than any multithreaded
snort. Think of the same problem: How should for example snort handle
a gone database connection?

Best regards
