> The pid file will allow snapinstaller to be run as fast as possible without overruns. Also it will recover from a last failed run should an older snapinstaller process no longer be running.
> Avoiding overruns means that snapinstaller can be run as fast as possible, but without suffering from the performance issue described here:
> http://wiki.apache.org/solr/SolrPerformanceFactors#head-fc7f22035c493431d58c5404ab22aef0ee1b9909
> This means that one can do the following
> */1 * * * * ..../bin/snappuller && ..../bin/snapinstaller
> Even with a 'properly tuned' setup, there can be times where snapinstaller can suffer from overruns due to a lack of resources, or an unoptimized index using more resources etc.
> currently the pid will live in /tmp ... perhaps it should be in the logs dir?
