This seems to happen if your repository consists of many large binary 
files, especially many large binary files of several versions that do 
not deltify well against each other. Perhaps it's worth adding gzip 
compression detecion to git? I imagine more people than me are tracking 
gzipped/bzip2'ed content that pretty much never deltifies well against 
anything else.
