Couldn't push: I tested with --disable-atomics --disable-spinlocks and
the tests fail because the semaphore for the atomic variables is not
always initialized. This is weird -- it's like a client process is
running at a time when StartupXLOG has not initialized the variable ...
so the initialization in the other place was not completely wrong.
I'll investigate after lunch. Here's v16.
