wine dll loader

[Vyacheslav Napadovsky]

Thank you, Vincent for advice.

After some investigation I've come to conclusion that
std::this_thread::sleep_for may cause .dll unloading if I'm using
Windows native msvcr120.dll.
And I have to use native msvcr120.dll because some functions that my
thirdparty libraries requires are missing.
Can you please advice further steps to fix this issue (because I think
some other apps may be affected by it)?
// for my app I'm already figured out architecture (init/deinit)
redesign outside DllMain.
