Let me try again.

Please add "running" in the above sentence "... without running X" or similar.

With the loader.h in place you shouldn't need this.

You don't need/want to do this, if the variable is set. Environment

Although as getenv() can return empty string, imho one can just ignore

Missing close(fd) ?

Missing close(fd) ? Which reminds me that patch 2/4 needs an update.
