Well, this is pretty simple to me.
Remember the old days with eAccelerator?
As soon as you change the codebase, the cached data needs to be flushed.

If I fully unterstood ZO right, the result of the compiled code is being 
cached, thus reducing compilation overhead (and boosting PHP speed).

So this behaviour is annoying, but no real mystery to me :)
