A denial of service can be constructed from such printout, so this can't
stay in an release version. Think of what
#include <signal.h>
static void si(void) { }
int main(int argc, char *argv[])
{
signal(SIGILL, sh);
while(1)
asm volatile("mfc0 $0, $0");
}
would do if each exception would result in a line in syslog.
