OK, points essentially taken and will push through another patch in
due course ... just a couple of points, though:

* Did the defensive stuff because bad guys might inject evil code
rather than because I thought in normal run of execution there would
be an issue - guess I just have to forget that?

* On the semaphore - what should I use? Uninterruptible? Spinlock?
Aren't there big downsides to them also?
