Additional timings. After a first clone (from the PBUILD build) doing "sage -br" to get back to the main branch took 8m29s. Then doing a new clone from the main branch took 7s. Then another "sage -br" is almost instantaneous, after which yet another clone is only 7s.
I'm not sure any of this helps, it certainly seems bizarre to me.
