So, let me summarize the issues:
- if the tree is pushed into while files are being actively read
  (e.g. built from), the build will get an inconsistent state
- even worse if one of the files is open for editing or is being written
  into: the file will get corrupted
- if there are uncommitted changes in the tree, the push is denied

Are there others?
