Good memory ;)

Can you mention an example of Windows popping up an error message "function
foo baz called with invalid parameter ..., what do you want me to do?".
See? Me neither...

And how do you want to """prevent""" anything?? Forget it...

The kernel developers code according to their very own rules, they're the
ones to design stuff properly and thus fully know error conditions and
corner cases of the code they're designing from scratch.
We *absolutely* don't - especially when considering MSDN "correctness"
<expletive deleted>.

Any additional error checking in Wine that's *not done by Windows* to make
(semi-)abnormal code flow keep running is A Very Bad Thing (tm).

That may well be the case, but I sure as hell don't want to even increase
my trouble by orders of magnitude by waiting a lot longer in this error case...
