Hi Efraim,

Right.  Unfortunately, these timeouts are too short for many slower
machines, such as 32-bit ARM systems.  Bone Baboon has also recently
reported being unable to build 'glib' on a 32-bit i686 system due to
these timeouts, even when making extreme efforts to reduce load from
other processes.

I think that this recently-reported bug (<https://bugs.gnu.org/48024>)
demonstrates that we can't safely remove the substitution.

I don't see how a build test on your aarch64 board is relevant here.
As the comment above the 'increase-test-timeout' phase indicated, the
timeouts were increased for the sake of slower 32-bit ARM boards.

I think that we should re-introduce the 'increase-test-timeout' phase
for all systems on the 'core-updates' branch.  Is there a disadvantage,
besides having to wait a couple more minutes if a test fails to
terminate?

What do you think?

      Regards,
        Mark
