commit e650c2b33e4fefc0589751b3958bd3b5d3b423ac
Author: Alistair Leslie-Hughes <leslie_alistair@hotmail.com>

Ensure fds are closed when exec functions are used.
When usng shm_open, FD_CLOEXEC is set explicitly.
However when using memfd_create, we must pass the MFD_CLOEXEC flag
to ensure the same fcntl value (FD_CLOEXEC) is set.
Fixes #1394
