No idea. Is there anything in the etop output that makes you think  
transactions are a problem?

I think I only have one transaction in my code, everything else is  
dirty ops.

I also tried making all the tables ram_copies, just for the sake of  
it. I still get gen_server timeouts.

I'm trying to profile with eprof now. I started profiling but my test  
harness hangs waiting for the games that will never finish.

I thought I'd try to connect to the node, find that test process and  
kill it.

Tools are failing me and the saga continues!
