Research direction

Start by reviewing testsigint.zip and the attached traceback_checksignals.patch files, then inspect the current implementation of PyTraceBack_Print() and PyErr_CheckSignals(). Reproduce the signal-handling failure and compare the behavior with the proposed patches; done means the traceback prints correctly when a signal is pending but PyErr_CheckSignals() has not been called.
