Issue #4289 has been updated by Eric Wong.

File 0001-test-socket-test_unix-fix-test-failures-from-rb_mod_.patch added

0002-error.c-rb_mod_sys_fail-use-subclass-and-cache.patch breaks
existing test cases that use assert_raise/assert_raises.  This
may be a dealbreaker for the patch, unfortunately...

Actual code that uses "rescue Errno::EAGAIN" is unaffected.
Anyways I have a patch to fix the failing test case I encountered if
breaking existing Test::Unit code is alright...
