[PATCH 2/2] sys_cmd error handling improved in the following ways: (1) If the subprocess exits nonzero then the exit status is unpicked and logged. (2) If the exec in the child fails, the command and errno string are written to stderr (which should end up in secnet's usual log output). (3) _exit() is used instead of exit(), to avoid any possibility of craziness with stdio/atexit/etc.

I'm not sure what git-send-email was playing at there.  The description 
in a more readable form:
