I followed something similar to that and ran the DTrace script 
filebyproc.d and discovered that every time I switch notes I'm hitting 
a fault and/or loading a NIB file to get the viewer (text, web, or 
PDF) and that every time I'm doing those things Spotlight is opening 
up the following files about forty times each:

  1  17600                      open:entry mds .
  1  17600                      open:entry mds .
  1  17600                      open:entry mds 0.indexGroups
  1  17600                      open:entry mds 0.indexIds
  1  17600                      open:entry mds 0.indexHead
  1  17600                      open:entry mds 0.indexPostings
  1  17600                      open:entry mds 0.indexPositions
  1  17600                      open:entry mds 0.indexDirectory
  1  17600                      open:entry mds 0.indexCompactDirectory
  1  17600                      open:entry mds 0.indexArrays
[repeats 45 times]

So it's not Core Data after all.  However, for some reason, accessing 
those files causes mds to go haywire.  Well, at least I have a head 
start on the issue and can try to see what's causing that.  This is 
really strange.  I suppose it's updating the access time or something, 
but even erasing the Spotlight database (by hand, from the install CD) 
didn't resolve this.  Oh well, I'll go file a bug...

Thanks for the lead!
