Hi!
This is just a FTR after the nice patch
https://git.libreoffice.org/core/+/9617bc9544cd569066ff187c3672a87fe28fe17f
from Jan-Marek.
With today's Version: 7.2.0.0.alpha0+ (x64)
Build ID: ed07eff77df5af3b214a3791b4455a743ca35853
CPU threads: 12; OS: Windows 10.0 Build 19042; UI render: Skia/Raster;
VCL: win
Locale: ru-RU (ru_RU); UI: en-US
Calc: CL
I see this deadlock (which I also saw before that change, so it is not
any kind of regression from that change).

The deadlock is because clipboard thread tries to acquire solar mutex
held by main thread (acquired in WinSalTimer::ImplHandleElapsedTimer).
At the same time, main thread calls a method of an COM/OLE object
created in the clipboard thread: it gets it in
CWinClipboard::getContents, and CDOTransferable::create indirectly calls
its CEnumFormatEtc::Next.
Since we (correctly) initialize the clipboard thread for
appartment-threaded object concurrency (see OleInitialize called in
CMtaOleClipboard::run [1]), any call to methods of COM/OLE objects
created in that thread are serialized to that thread. Hence the wait in
the main thread (CCliModalLoop::BlockFn).
I suppose we must check to release solar mutex before any blocking calls
to clipboard thread, including explicit waits (like
CMtaOleClipboard::getClipboard that posts a message and then waits) and
implicit waits like described above, calling COM methods of objects
known to be created in a different thread.
