* Signal.trap now always returns the previous handler for the trapped signal, or the string DEFAULT or SYSTEM_DEFAULT as appropriate. This is the same behavior as MRI. * Signal 0 (SYSEXIT) in MRI is now implemented. If a SYSEXIT trap is set, it will be executed as the JRuby runtime is torn down. * Added taint checking for trap handlers, for MRI parity * Added reserved signal checking for MRI parity * Fixed a bug that previously prevented IGNORE from being sent as a trap * Un-excluded a number of Signal tests
