Ok, maybe I need some vacations...
Last try, from the source "mozilla-release/image/src/RasterImage.cpp":
RasterImage::DecodePool::DecodePool()
: mThreadPoolMutex("Thread Pool")
{
if (gMultithreadedDecoding) {
mThreadPool = do_CreateInstance(NS_THREADPOOL_CONTRACTID);
if (mThreadPool) {
mThreadPool->SetName(NS_LITERAL_CSTRING("ImageDecoder"));
uint32_t limit;
if (gDecodingThreadLimit <= 0) {
limit = std::max(PR_GetNumberOfProcessors(), 2) - 1;
} else {
limit = static_cast<uint32_t>(gDecodingThreadLimit);
}
mThreadPool->SetThreadLimit(limit);
mThreadPool->SetIdleThreadLimit(limit);
nsCOMPtr<nsIObserverService> obsSvc = mozilla::services::GetObserverService();
if (obsSvc) {
obsSvc->AddObserver(this, "xpcom-shutdown-threads", false);
}
}
}
}
