In fact the issue is not specific to glibc; any file in use will lead
to the same problem. The kernel wants to delete the old file from the
filesystem, but since it is still in use it can't do that.

This does not solve the problem.

3. Tell the kernel not to delete the file when it is overwritten. How?
By creating a hard link. When the file is no longer used (next reboot)
it is safe to delete the hard link. This is more satisfactory than the
previous solution but it is not still perfect.

Any other idea?
