Performance dies after doing massive amounts of IO.read calls
-------------------------------------------------------------

                 Key: JRUBY-2640
                 URL: http://jira.codehaus.org/browse/JRUBY-2640
             Project: JRuby
          Issue Type: Bug
         Environment: MacOS 10.5.3
            Reporter: Wayne Meissner
            Assignee: Thomas E Enebo
         Attachments: bench_io_read.rb

When running a modified version of test/bench/bench_io_read.rb, the RSS of the 
java process grows until it hits 500M (the specified limit).

At that point, each iteration of IO.read takes about 100x longer than it should.
