This is GCJ?

And the collector is issuing the message because it fears that it cannot avoid 
using addresses that it would rather blacklist?

Does GCJ use typed allocation?  Is there any need for a conservative estimate?  
If the collection can be precise then there is no need for blacklisting and 
this message could conceivably be disabled.

What am I missing?
