I'll have to assume so, for now.  The part I find really interesting is 
that there isn't any code in the test suite that uses threads, so why is 
there a message reading "Switching to Thread 1024 (LWP 6025)"?  Of course, 
I know nothing of gdb; the only C debugger I've ever used was CodeView, and 
that was a long time ago.

The other weird thing is that the error shown is for code in a function 
that hasn't changed in quite a while; almost since _once.pyx was first written.
