   2 /* Sigcheck is similar to intrcheck() but sets an exception when an
   3    interrupt occurs.  It can't be in the intrcheck.c file since that
   4    file (and the whole directory it is in) doesn't know about objects
   5    or exceptions.  It can't be in errors.c because it can be
   6    overridden (at link time) by a more powerful version implemented in
   7    signalmodule.c. */
