Errno::EACCES when multiple files are open simultaneously

[jbeyer05]

This is a re-post of a bug listed in the CodeHaus bug tracker (JRUBY-6022) that still affects 1.7.18.
When a large number of files are open without closing the handles, the user receives an EACCES exception. This is not the case with cruby. Code used to demonstrate difference between jruby and cruby below.
