core files from hobbit_larrd

[Tom Georgoulias <tgeorgoulias (at) nandomedia.com>]

I'm getting a bunch of core files in my ~/hobbit/server directory. 
Here's an example:

bash-2.05b$ file core.3770
core.3770: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV), 
SVR4-style, from 'hobbitd_larrd'

I wasn't seeing these before I upgraded to RC3.

From hobbitd.log:
