Trying today, the roles of the machines have reversed; the one failing
on Friday passed today and vice versa. The passing test:
```
$ time go test -test.short cmd/go
ok cmd/go 339.070s
real 5m45.804s
user 1m38.821s
sys 0m49.390s
```
The version is a lie - there is a change to malloc.go increasing the
heap size to 1TiB, but no other change and without that change I have
seen the same behaviour.
(I have had a response from one of the admins and the head is a VM
where there may be fs contention - the time result below supports
this).
The failing test (time:real 10m43.407s user 0m42.286s sys 8m9.984s):
```
