[Bug 51429] Sakura no Uta: spams RtlpWaitForCriticalSection

[WineHQ Bugzilla]

--- Comment #3 from Zebediah Figura <z.figura12 at gmail.com> ---
All that message means is that a thread has been blocked on a critical section
for more than 5 seconds. A critical section is a sleeping mutex, but generally
shouldn't be held for long periods of time, and if it does, it's probably
application misbehaviour. But the "?" means that it's one the application
created (not Wine), so whatever the application is doing to hold on to that CS
is probably its own fault. Not certainly, but probably, and given there's
nothing visibly wrong, it's not worth investigating.

Most software in the Unix world is on a completely open-source stack, and is
completely implemented at least according to its own specifications. As a
result a log message either indicates a problem in the component itself, or in
a higher or lower component, any of which deserve fixing. Wine is unique; we
don't control the software that we run, and we can't fix its bugs. At the same
time, large parts of Wine are simply not implemented, because no application
has needed them yet. Hence it's very easy for applications to trigger ERR or
FIXME messages meaning either that the application is doing something broken,
or it's hitting a code path that isn't (fully) implemented in Wine. But often
neither of these actually matter in practice. Hence we view log messages as a
debugging aid—a FIXME *can* be harmless, or it can be the root cause of a
failure—but not as a symptom of a bug in themselves (in most cases).
