On my VPS I have limited memory and thus limited worker PHP processes. WP-Piwik did regularly hang my VPS and this is because there is a bug in version 0.8.10, which causes the tracking code to be fetched from the Piwik server each time time and thus creating a new unneeded PHP worker process.
BTW, I was confused, because the readme.txt says 0.8.9 instead of 0.8.10.
Although this seems to be fixed in the next version (trunk), here is the fix:
