Certainly. :-) After the initial window refresh of all the files, select any
15 or so consecutive objects (location seems to make no difference for me),
smack the delete key and confirm.

Ok, I see what happens. Client opens each file in turn, sets delete on close,
then closes - we send a changenotify - client sets another change notify up
on the directory - repeat until all the files are deleted, then the client
(explorer) re-scans the directory using findfirst/findnext with a * wildcard.

It's the last action that's causing a stat on each remaining file in the
directory. I don't see anything out of the ordinary here....


Hmmmmm, right. I'm seeing stats on each delete on AIX (like a 10-15 second pause between each) and on the re-scan.

The deletes on FC3 were snappy followed by a long pause which was the rescan.

<taps chin>

I wonder why all the stats are happening on AIX between deletes and not on FC3.
