The computation of recent_avg_pause_time() is susceptible to unbounded error
as the JVM ages because of the way it's currently computed. (See comments
section for a description of the problem and a solution.) The susceptibility to
the error depends on the occurrence of specific patterns of very short GC's
alternating with long periods of no GC. It turns out, though, that in the
cases where this test fails in the nightlies, the timestamps generated by
the JVM (on Linux/amd64) themselves are "bursty" (time presumably does not progress
smoothly -- it jumps forward then stalls for periods of time with no
forward progress; this defect should be independently and separately
investigated to see if the JVM time-service or the undelying os/platform/hardware
might be defective here) -- this turns out to simulate precisely the condition
of a JVM that has lived for a very long time and then sees a burst of very
short GC pauses. Computing the rcent_avg_pause_time_ratio() in a slightly
different way should protect us from this increasing coarseness/error
as the JVM ages. See the comments section for more details.
