STINNER Victor <vstin...@redhat.com> added the comment:
Robert Boehne: pyurandom() uses _Py_open_noraise("/dev/urandom", O_RDONLY)
which uses O_CLOEXEC if available. If this flag available? Does it work?
Please try to build attached urandom.c.
Example on my Fedora 29:
open O_RDONLY succeeded
read(16) -> 16
open O_RDONLY | O_CLOEXEC succeeded
read(16) -> 16
