I think this should be fine.  I've been using O_CLOEXEC on Linux for
years without running into ancient version/portability problems.

As for different libc implementations, the two major ones which GoT is
likely to be linked against are libc and musl, both of which support
the O_CLOEXEC flag, so I think we should be OK with this.
