That is accurate for KMail in cvs, but not when "Sam's" patch has been 
applied (this patch has been posted to the KMail list a few times by me).

With Sam's patch applied the index is lazy and information is retrieved from 
disk on demand. Index records are now just proxy classes that return (shared) 
QStrings and ints, without owning any data themselves. (Well they cache the 
status field, have a private d pointer and take ownership when the are 
written to ie. modifed).

Sam's patch also has many other optimizations, in fact it turns out that 
QListView is not the bottle neck I originally thought it was.

BTW I don't subscribe to kde-devel.

BFN,
Don.
