if (sentinel.ref()) ++errorCount;
if (!sentinel.deref()) ++errorCount;
lockCount.ref();
mutex.unlock();
if (mutex.tryLock()) {
if (sentinel.ref()) ++errorCount;
if (!sentinel.deref()) ++errorCount;
lockCount.ref();
mutex.unlock();
}
}

/* Right now, we're inside the custom message handler and we're
* being qt_message_output in qglobal.cpp. After we return from
* this function, it will proceed with calling exit() and abort()
* and hence crash. Therefore, we call these logging functions such
* that we wrap up nicely, and in particular produce well-formed XML. */
