It's not an review but an issue i found. the patch may broke CEF Based Application running? Tried `Steam for Windows` and hang when creating gpu-process. do `rmmod ntsync` then working again. checked log `026c:0278:trace:sync:NtWaitForMultipleObjects wait_any 1, alertable 0, handles {0x138}, timeout -30.0000000` `0x138` finally didn't get `NtSetEvent` and wait again and again Also tried cef demo, it stuck when loading website. ============================================ And ``` if ((ret = inproc_wait( count, handles, wait_any, alertable, timeout )) != STATUS_NOT_IMPLEMENTED) { TRACE( "-> %#x\n", ret ); return ret; } ``` Is it not necessary to add `NtYieldExecution` when return timeout? just like `server_wait` do -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7226#note_102046
