If you're looking for some 'official' validation of what you see, 
I'm not sure that you'll find it here.  It's not that we wouldn't like
to give it (or even refute your findings ;-) ).  It's just that I don't 
believe anyone has done as much analysis of this issue as you have.  
Certainly, the values you report (89000 files occupying 1.4GB of space) are
not, in and of themselves, an obvious red-flag.  If you'd like to get a 
better handle on the situation (and help the list understand your problem as
well), it would be worthwhile to run strace on this process and look
for any suspect results.  Be warned.  This will generate a huge file
with lots of output, most of which is not going to indicate any problems.
However, if you can help isolate a problem area, it may be easier for 
someone here to diagnose the problem and offer a fix... or at least an
explanation.

Sorry I don't have the magic bullet for you.
