A bug report called " f->output_data.w32->menubar_widget
uninitialized?" and suggesting to check some system calls return
values as part of some non-very-specific hypothetical bug is not a
"code change we should not forget", IMHO. As I've said in the previous
message, I think you're talking about your suggestion of checking
every system call. If so, please create a wishlist bug report called
"All system calls' return values should be checked", or somesuch, so
at the very least people perusing bug reports can know at a glance
that it is a wishlist and what it is about. I promise I won't close
that bug (though I won't likely do much about it, either).

No, because I still don't know what the problem is.

Your "problems with race conditions" do only happen to *you*, on
*your* patched Emacs. So, if you want to help tracking them, you
shouldn't "suggest" anything (IMO, I hasten to add). Patch your Emacs
with debug macros to you heart's content, and when you do find
something wrong, reproduce it with the stock Emacs and file a
(detailed, step-by-step recipe'd) bug report about it.

"We"? You're talking about code that you've changed in non-trivial ways!

Then, what are we discussing about?

It is perhaps a fine suggestion, if you care to explain what is "the problem".
