    Description

      A complex iterator initialization took a long time (hours).

      The SimpleTimer cleanup was blocked on the tablet lock.

      After the scan was stopped and the SimpleTimer ran the logGCInfo saw a large jump in GC time. In this case it was 60s over the course of 2 hours between checks.

      The tabletserver determined that GC was causing unacceptable delays and killed itself.

      The check should take into account the time difference between checks, and probably log a warning if the time difference is much larger than expected.
