  On an ARM processor I'm playing with, before that patch:

We have tried to stick to a limit of 1 s on a reasonable current
computer. Most tests should use much less, if possible.

(We have some undocumented environment variables, e.g.,
GMP_CHECK_REPFACTOR which can be used to run more or fewer
tests.  We use that for our slowest and fastest test systems.)
