here is one (of a number), in looking at the insert code. Basically, you 
prime the cursor for
insert, stuff in some values, then do in insert. The cursor is then
invalidated until you do another select (or you can say to leave it valid,
but the inserted values do not appear in the cursor until you do another
select).

This is total crap; it is 100% useless for something like Rekall. Imagine 
accessing a
database over the net, where there are (say) 10K records. Each time you
insert you have to reissue the select; also, you cannot tell reliably which
was the inserted record. So, the user has to wait ages, only for the form to
return to the first record (or maybe the last).
