rev-list doesn't try to draw a line from each commit to its parents.
That's the really intensive part.  So when gitk reads

	d56871cb0e6ceeca8e5435ff95409d78bed014f0 a046fe0cb8697bc97993b2e609688ff5e89e3e9

it must remember this line at least until it sees a line starting with
a046fe0cb8697bc97993b2e609688ff5e89e3e9.

Best regards
Uwe
