Windows regrtest failures

9 fails unexpected:

test_classpathimporter test_java_integration test_marshal test_netrc test_old_mailbox test_pkgimport test_popen test_shutil test_urllib2

• test_classpathimporter - file handles, though not a straightforward fix, org.python.core.ClasspathPyImporter is the culprit
• test_java_integration - jython.bat needs (or 'should' as there's absolutely nothing subprocess can do about it) to strip surrounding quotes from command line arguments
• test_marshal - recursion tests blow out stack. jython.bat sets Xss512k (and posix sets Xss1024k) but windows seems to need Xss1280k to pass
• test_netrc - file handles
• test_old_mailbox - file handles?
• test_pkgimport - file handles? but passes over here..
• test_popen - http://bugs.python.org/issue1559298
• test_shutil - apparently java.io.File.delete completely ignores ntfs permissions set by test_on_error???
• test_urllib2 - ?

Also test_mailbox fails horribly and is temporarily disabled from regrtest --expected
