This closes patch: [ 960406 ] unblock signals in threads although the changes do not correspond exactly to any patch attached to that report. Non-main threads no longer have all signals masked. A different interface to readline is used. The handling of signals inside calls to PyOS_Readline is now rather different. These changes are all a bit scary! Review and cross-platform testing much appreciated.
