When clicking the test history at any level for a job with say 3,000 builds, the
history table will load a few hundred rows and then hang, and the graph will
never load. After a minute or two the hudson instance will be completely
unresponsive or give Out Of Memory errors. Hudson will not even respond to a
SIGTERM, I must do a SIGKILL to stop it.

So in other words, the test history feature doesn't seem to work in projects
where it would matter the most, and can be quite disruptive as it will bring
down Hudson and all its jobs
