Yeah, this printout is consistent with Alexander's observation that
it's ecpg threading tests that are getting stuck:

All the other processes belonging to pgbf are test driver processes
that would be waiting for these two.
Since we're not seeing comparable failures on other animals,
I tend to agree with his diagnosis of a bug in 9.3's malloc library.
