Description changed by kermit:

Old description:

> When selecting logs twice the size seems to take 16x as long to load,
> which leads to obvious problems.  A 2.5MB log takes about 5s to load on
> my system, but a 5MB log takes about 90 seconds.  Much bigger than that
> and I just kill it. These are wild guesses on these figures but you get
> the point, it might be o(n^3) or o(n^5) or o(n^3+n^2) or something
> equally ungood besides (o^n).

New description:

 When selecting logs twice the size seems to take 16x as long to load,
 which leads to obvious problems.  A 2.5MB log takes about 5s to load on my
 system, but a 5MB log takes about 90 seconds.  Much bigger than that and I
 just kill it. These are wild guesses on these figures but you get the
 point, it might be o(n^3^ ) or o(n^5^ ) or o(n^3^ +n^2^ ) or something
 equally ungood besides (o^n^ ).
