Mmh wait, actually ExitProcess acquires the loader lock before terminating all other threads. So it seems that GetModuleHandle can acquire another lock? Will keep investigating...
Ah ok, it's `LdrpSnapsLock`: ``` ntdll.dll!RtlEnterCriticalSection() ntdll.dll!LdrpAddUnicodeStringToSnapsBuffer() ntdll.dll!LdrpLogInternal() ntdll.dll!LdrGetDllHandle() KERNELBASE.dll!00007fff76ddfc86() ``` It's acquired regardless if loader snaps is enabled or not. Of course that lock can be acquired when the...
