I made some progress:

Upgrading to the recent OpenSSL test release [1] got me past the 
problems I had been debugging.  Unfortunately I ran into a new problem 
in test_threading's check of SetAsyncExc, which gdb tells me is 
somewhere in PyInterpreterState_GET(), but only half the time when I 
evaluate that function in that thread in gdb.  I'll report back if I can 
get something more concrete.
