Can you explain where this would occur?

If you're sitting in branchB, you can clearly block r10 from branchA.  But if 
you're in branchC, then you won't pull r10 through via branchB since branchB has 
it blocked.  However, if you've set up branchC to pull revisions directly from 
branchA, then it sounds like branchC should look in branchB's svnmerge-blocked 
property to block it?

So I don't see how r10 can end up in branchC unless you set up branchC to merge 
from branchA.
