I have not been following current but I read any emails sent directly to 
me without a mailing list in the cc.  I also was not aware of this.  I had 
not heard of any filesystem corruption problems at all.  If there are any, 
I also am not comfortable with enabling it by default.  I want to fix that 
first.

I have blocked off next week to work on this.  I already sent an email out 
to current@ requesting bug reports.  Please if you have anything else let 
me know immediately so I can prioritize it and start investigating.

Thanks,
Jeff
