    Description

      The following is from a run of SPECjvm98 with a 64-bit fastdebug JVM (jdk7-b24) on a machine w/28G of RAM:

      [GC [PSYoungGen: 28418K->480K(1888448K)] 30878K->2939K(2195648K), 23.4082886 secs] [Times: user=23.40 sys=0.04, real=23.41 secs]

      23 secs is way too long to copy the 480K of data that survives in the young gen.
