   It looks like the table delete time is proportional to the number of 
transactions.  Using 125 transactions the delete completed in 3 seconds.  With 
250 it took 30 seconds.  So, either the delete is waiting on transactions to 
complete before it can get a lock - or if it is calling cancel, then that takes 
longer with more transactions.
   
   I tried a version that waited for 0 transactions before issuing the delete 
and it would need to wait for about the same time as the delete is taking.  
   
   Another observation from that test, the admin command seems fairly heavy 
weight.  If I slept 500 ms between transaction count checks, the admin command 
would show up in top with cpu usage pegged.
