Add memfd_create() and constants MFD_ALLOW_SEALING, MFD_CLOEXEC to the os module. A glibc wrapper for memfd_create() is not available yet but the interface has been standardized. http://man7.org/linux/man-pages/man2/memfd_create.2.html https://dvdhrm.wordpress.com/tag/memfd/ |

Maybe useful at mmapmodule.c replacing
/* SVR4 method to map anonymous memory is to open /dev/zero */
fd = devzero = _Py_open("/dev/zero", O_RDWR);
tagname is unused at UNIX version of new_mmap_object() so if provided something like could be added for Linux only
fd = memfd_create(tagname, O_RDWR);

https://buildbot.python.org/all/#builders/99/builds/2738 is failing because some HUGE TLB constants are not defined on Gentoo. |

Davin, Pierre, it looks like this could simplify lifetime management of shared memory pools, what do you think? |

From a quick skim at the man page of memfd_create, this looks promising. |
