Commit 5016959ce8c1eed9d354822f01edc4b509e4aa9d in lucene-solr's branch
refs/heads/master from Shalin Shekhar Mangar
[ https://git-wip-us.apache.org/repos/asf?p=lucene-solr.git;h=5016959 ]
SOLR-13082: A trigger that creates trigger events more frequently than the cool
down period can starve other triggers.
This is mitigated to some extent by randomly choosing the trigger to resume
after cool down. It is recommended that scheduled triggers not be used for very
frequent operations to avoid this problem.

> A trigger that creates frequent events (such as ScheduledTrigger) with period
> less than the cool down period can starve all other triggers. This is because
> we execute triggers in the same order each time so if the scheduled trigger
> happens to be the first in the list then after every cool down period, the
> scheduled trigger can create another event and the cycle repeats.
