merge revision(s) 43373: [Backport #9036]
* io.c (rb_io_reopen): create a new, temporary FD via rb_sysopen and
call rb_cloexec_dup2 on it to atomically replace the file fptr->fd
points to. This leaves no possible window where fptr->fd is invalid
to userspace (even for any threads running w/o GVL). based on the
patch by Eric Wong <normalperson@yhbt.net> at [ruby-core:57943].
