With the Windows/x86/x64 memory model, is the write to
vm_getting_terminated guaranteed to be observable by java_start()?
In the general case, not immediately. For the threads actually of
interest the logic that tells the threads to terminate happens after the
write to the flag, and that logic contains sufficient "synchronization"
that if the termination logic is correct then the flag must also be visible.
