Subject: Fix problem discovered by Barry: if you hit ^C to
 sys.stdin.readline(), you get a fatal error (no current thread).  This is
 because there was a call to PyErr_CheckSignals() while there was no current
 thread.  I wonder how many more of these we find...  I bnetter go hunting for
 PyErr_CheckSignals() now...
