BTW, I searched the buildfarm logs of ECPG failures to see if I could
find anything related to this, and noticed that there were a fair
number of Windows-machine failures in the thread/prep test. They don't
all look quite alike, but this one is representative (and the most
recent):

I suspect that this might arise from a pthread_once failure
associated with the actual_connection_key variable.
