Ummm... right you are. Well, I've fixed the 'zillion files' problem.
You need to exit with a non-zero error code (JREMOVE) is good.
Alos JFAILNORETRY is good:
#define JFAIL 32 /* failed - retry later */
#define JABORT 33 /* aborted - do not try again, but keep job */
#define JREMOVE 34 /* failed - remove job */
#define JHOLD 37 /* hold this job */
#define JNOSPOOL 38 /* no spooling to this queue */
#define JNOPRINT 39 /* no printing from this queue */
#define JSIGNAL 40 /* killed by unrecognized signal */
#define JFAILNORETRY 41 /* no retry on failure */
#define JSUSP 42 /* process suspended successfully */
#define JTIMEOUT 43 /* timeout */
#define JWRERR 44 /* write error */
#define JRDERR 45 /* read error */
#define JCHILD 46 /* no children */
#define JNOWAIT 47 /* no wait status */
