If APC is enabled on the piwik server, cache files written by the CacheFile
class are stored in the opcode cache. This causes disk io problems when doing
things like loading weblogs into piwik with the import_logs.py script,
especially when running in --disable-bulk-tracking mode. In this scenario,
apache write IO quickly reaches 100% and slows the import to a crawl.
Hmm. Seems like all of the tests that failed were related to composer install failing?
Sorry about that! This is an issue when new contributors like you are so kindly doing a PR but our build was already failing unfortunately... we really want to avoid this in the future see #5954
PR looks good, this is a nice edge case improvement!
