/* Sigcheck is similar to intrcheck() but sets an exception when an

interrupt occurs. It can't be in the intrcheck.c file since that

file (and the whole directory it is in) doesn't know about objects

or exceptions. It can't be in errors.c because it can be

overridden (at link time) by a more powerful version implemented in

signalmodule.c. */
