bcea21c06a fixed memory bug in client scams; better debugging status during merge backpressure

07b35f4e20 scattered, and poorly tested fixes. finer grained latching for tree nodes; throttle c0-c1 merge when c0 is small; fix delta computations for c0 throttling; disable short pauses for c1-c2 merge. this gets the bulk load throughput up to 8500, but workloada is still slow

4050475de9 more bugfixes / cleanup. latching is probably overly conservative at this point, but ycsb bulkload finally seems to work
