It's a Linux kernel repository. Git receive-pack is going over 200MB and getting zapped. I don't understand why the process is so large. I am compiled with -DNO_MMAP.

I think I have a achieved a work around. I rsync'd in my last several weeks of changes. Now I can 'git push' small amounts of changes without getting killed.

I'm begging dreamhost to simply install git. Installed commands don't get zapped.
