That said I would imagine more of this should be done on initialization...? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4449#note_54466

Either we should explicitly block the read thread, or shut it down and restart it. The latter is probably simpler. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4449#note_54465

The codec_data introduced in 1/6 isn't validated in the tests. Why is that? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4449#note_54461

[PATCH v27 0/3] MR3504: ntdll: An implementation of SRWLOCK that closer matches Windows'.
by Yuxuan Shui (＠yshui) 30 Nov '23

This comes from behavioral study of Windows, which doesn't seem to check if the lock is actually exclusively held, and just simply decrement the value stored in the lock. This fixes a dead lock which prevents WeCom from starting up. -- v27: ntdll: allow SRWLOCKs to be quickly re-acquired ntdll: An implementation of SRWLOCK that closer matches Windows'. https://gitlab.winehq.org/wine/wine/-/merge_requests/3504
