Public bug reported:

If you look at graph with CPU usage in this post
http://www.mysqlperformanceblog.com/2008/12/18/xtradb-in-cpu-bound-benchmark/

you see XtraDB has very irregular CPU-usage, while -std and -plugin has
more uniform (with dip at flushing time).

Probably it is related to adaptive_checkpointing, please investigate the
issue.
