On my PC when I delete a 10K file, filemon shows 18,000 disk access
calls, almost all in the recycle bin. After emptying the recycle bin the
delay (and activity) is gone.

If you delete an SVN working copy, there is a vast number of small files
hidden in the .svn folders which I think kills recycle bin performance.
Moral: if you delete a WC, bypass the recycle bin (shift-delete).

But I don't think this is really the answer to the original question. It
is not a problem I have ever seen or heard of, so it would seem there is
some pathological condition common to the home and work PCs. Long delays
with no CPU or disk activity would be symptomatic of attempted network
access, so Will's suggestion of using Ethereal (or Packetyzer) seems the
best hope of tracking this one down.

Please let us know what you find out.
