Besides, there is a slight delay (~1-2 sec) in kernel repo (writing the cache out?) on exit. I used gitk from this commit: commit 5cd15b6b7f87dc61f729ad31a682ffc394560273 Author: Paul Mackerras Date: Thu Aug 30 21:54:17 2007 +1000 gitk: Add a cache for the topology info BTW, what should happen if I try running many gitks in the same repo? Is the cache safe for concurrent writing by them? Is it NFS-safe?
