hmm, thats unfortunate, I've tried to debug it a little bit but as soon as I add this:

...
} while (rc == -1 && errno == EINTR);
std::cout << std::chrono::system_clock::now().time_since_epoch().count() / 1000 << " errno: " << errno << " rc: " << rc <<  std::endl;
for (auto& stream : m_streamList.values())
...

in CurlStreamScheduler.cpp, the issue goes away (and nothing shows in any terminal unfortunately, though I added AllocConsole() earlier)

It seems like ::select() is returning constantly, that could maybe explain the hot path as shown in the attachment earlier.

I'm not sure how to continue.
