OK, so its well packed and C Git behaves nicely.  :)

So it must have been the massive flurry of UI updates that I used to be doing during revision walking. I backed it off to at most 4 times per second, which seems to help.

FWIW I just pushed another update out:

 * re-activates the old preferences for hiding/showing the commit
   message and file list;

 * word wrap setting for the comment viewer area;

 * saves the geometry (split pane positions) of the history page
   in a hidden preference;

 * copy and select all global actions (Edit->Copy aka Ctrl-C) now
   works to copy:
     - selected text in comment area;
	 - selected path names in the file list;
	 - commit SHA-1s of selected commits in DAG;

 * the window cache is now managed by Eclipse workspace settings
   when inside Eclipse;

 * the window cache now defaults to 8k/10m/10m/no-mmap as that is
   working very well for me on multiple systems;

 * global workspace preferences (Team -> Git) now shows the history
   preferences and the window cache settings
