I agree that it's not a Samba logic problem ... more like a Samba porting
problem?
And I don't think we can just blame JFS2 and/or AIX either because deleting
files in that directory directly on the box or even through NFS is orders of
magnitudes faster (minutes vs days to delete all the files in a directory
with 150K files).
