  * Can we use tid?

  * This blocks the syslog https://patchwork.sourceware.org/project/glibc/list/?series=8031
 * Siddhesh notes that DNS tests no longer depend on proc mount.
  * However we still have tests that use DNS and can fail.
  * They need to be ported to use the in-process test DNS resolver or changed.
 * Support DT_RELR relative relocation format review.
  * What is the status of DT_RELR for AArch64? Currently unimplemented.
