It does not interfere in the sense that the smp code cannot be used.  I 
believe it to work with it, and I did try it with -threads x, but I only 
have uniprocessor systems to test with; it could use exercising on 
multiprocessor/core systems.

I originally developed most of the work before Andreas' patch, then merged 
shortly before posting.

Sidenote: I'm working to split the patch into smaller patches and hope to 
have a new set of patches soon.
