RFR: 8157097 (was 8157133): CompactHashtableWriter SIGFPE when num bucket is zero

[David Holmes]

Hi Robbin,

This seems okay as an immediate fix for the test problem.

But I'm not completely clear on the bucket calculation logic as it seems 
we will put nearly 2x the number of entries in the first bucket. So 
please file a follow up bug for that - or discuss with someone more 
knowledgeable about the code to see if it is an issue or not.

Thanks,
David
