Hi Dale,

At this point I'm not sure what the problem was that caused the SEGV.  I
think its not the name conflict alone but also that the pre-existing process
the new process was conflitctin with was stopped because of a dnu.  I'll
send you the logs off list from when there was just a name conflict and when
there was a dnu.
