--- Comment #4 from Fabian Maurer  ---
So, I got to the bottom of this. Although I currently have no idea how to fix.
The following happens:

1) The programs calls FreeLibrary on dinput.dll
2) We go through (ntdll/loader.c) LdrUnloadDll and acquire loader_section
3) -> process_detach -> MODULE_InitDLL -> (dinput) DllMain
4) calls dinput_thread_stop, sends message to thread and waits for it to end
5) Thread returns, LdrShutdownThread gets called which tries to get
loader_section
6) Deadlock

dinput_thread_stop is a recent change:
