Subsystems, Shared Pools and Routing Entries

I'm just going through some steps to clean up a few things.  One thing is that the fine folks from MIMIX recommend we move MIMIX into its own pool.  Not a bad idea.  They recommend a shared pool rather than a private pool, and I'm okay with that.  I was able to create the shared pool with no problem by assigning memory to it (although I'm not sure how to remove it, but that's a different issue).  And then they say to set up the MIMIX subsystem to have only that shared pool using POOLS((1 *SHRPOOLx)).  Again, I understand.  And finally, make sure all the routing entries point to pool 1 (which they should have been already, and were).

So I'm okay with this.  Instead of all the MIMIX routing entries shoving jobs into *BASE, they'll now go into a shared pool.  Yay!

But while reviewing things I ran into a weird case.  I found a subsystem pointing to a shared pool, but the shared pool has no memory defined in WRKSHRPOOL.  For arguments sake, say it has POOLS((1 *SHRPOOL6)) but *SHRPOOL6 is currently defined with no memory.  How does THAT work?  Obviously it's wrong, but the subsystem is running.  Since that subsystem is incorrectly defined, do all the routing entries just get funneled into *BASE? That's what seems to be happening according to WRKACTJOB.
