* There is a memory leak for **environ and elements that should be

*
* The reason why environ is copied during g_process_set_argv_space
* so to be able to overwrite process title in ps/top commands to
* supervisor. In bsd there is setproctitle call which solve this,
* but currently it is not available for linux.
*
* The problem is that modules can add their own env variables to the
* list, which must not be freed here, otherwise it would result
* double free (e.g some version of Oracle Java). One might also would
* try to track which environment variables are added by syslog-ng,
* and free only those. There is still a problem with this, **environ
* itself cannot be freed in some cases. For example libcurl registers
* an atexit function which needs an environment variable, that would
* be freed here before at_exit is called, resulting in invalid read.
*
* As this leak does not cause any real problem like accumulating over
* time, it is safe to leave it as it is.
