I'd don't care if core files get generated, but I'd want some way to make 
sure that the core file doesn't fill the disk partition when it gets 
written.  I'm not sure how large the files can get, but I have had that 
problem in the past (on other software) with multiple GB core files 
completely filling a smallish / or /usr partition (as on a file server, I'd 
want to have as much space as possible go to the vice partitions.)

Would it be possible to reserve some space in the vice partition and have 
the core file written there instead?  (I suppose you could argue that could 
be worse, but in general I have much larger vice paritions than system
