Subject: [PATCH v3 2/2] Enable the close-on-exec flag for the debug log file
|
|
descriptor
|
|
|
|
On Linux this flag will make sure that no file descriptor is accidentally
|
|
leaked into potential child processes. While this is not a problem right now,
|
|
it is considered to be good practice these days when dealing with file
|
|
descriptors on the Linux.
