FWIW, on Debian testing, once solved the above problem of upgrading from 
`9.3.rc0` to 9.3.rc2`, thanks to Matthias, ptestlong gave exactly the same 
results as for the last two previous releases : one timeout (parigp.py), 
one cosmetic bug (gap_packages.py), one real bug (division by zero in 
abelian_group_gap.py).
