List, Paul,

after searching for a while on why Gitk sometimes consumes exorbitant amounts of memory I found a pair of minor issues and also a big one: the text widget comes with an unlimited undo manager, which is turned on be default. Considering that each line is inserted seperately, this piles up a huuuge undo stack ... for a read-only text widget. Simply turning off this undo manager saves about 95% of memory when viewing large commits (with tens of thousands of diff lines).

3 patches are about to follow:

 - turn off the undo manager,

 - forget already closed file descriptors and

 - forget the 'commitinfo' array on a reload to enforce reloading it.

I hope this finds you appreciation.

Thanks for the good work in tracking this down and making the patches.
I have applied the series.  Apologies for slow response (life has been
extremely busy for me this year).

Paul.
