--- Comment #2 from Dmitry Timoshkov <dmitry at baikal.ru> ---
As was noted in https://bugs.winehq.org/show_bug.cgi?id=20296#c74 one of the
remaning tasks is proper termination of dllhost.exe. That task itself consists
of at least two sub-tasks: call ISurrogate::FreeSurrogate() from ole32 when
CoFreeUnusedLibraries() deems that appropriate, and CoFreeUnusedLibraries()
relies on proper implementation of DllCanUnloadNow() in the loaded COM server,
and most (if not all) Wine DLLs simply return S_FALSE preventing them from
being unloaded, and as a result CoFreeUnusedLibraries() won't call
ISurrogate::FreeSurrogate().

So, while this bug is probably correctly marked as a regression, it actually
revealed a bunch of bugs in Wine, which need their own fixes.

Correct regression id should be f9cd4c915f1929db439aa527dc922cbfd9953327, since
this also affects not wow64 setups.
