Before starting to make this whole noexecute override behaviour configurable, it first must work reliable. In its current form there is no guarantee that the check_no_exec() function is actually called, because any other installed exception handler might decide to handle the exception itself. And as seen by the number of failing applications, this seems to happen quite a lot. This patch therefore makes check_no_exec() to be called before any other exception handler.
Any comments what is wrong with this one?
If the exception is not made visible to the app then there is no point in having one at all, we might just as well turn off the protection right away. What really needs to be done is to investigate the Windows behavior and determine which parts of the app memory should be protected and which shouldn't, depending on the exe flags etc. and then replicate that behavior.
