I tried to repro the RWCC issue I saw on TRUNK over on 0.20.5RC5 but
couldn't.  The multiput is missing from 0.20.  That might be helping
bring it on.  We could be burning CPU in 0.20 unnecessarily, but I
didn't see it.  I could apply the patch for 0.20.6 but would rather
have a citing of the "phenomenon" -- a spike in server load, java
process using thousands of percent of CPU -- before I do.
