Race in thread shutdown in imm32?

[Dan Kegel]

I'm seeing the following valgrind warning
in three out of eight runs under heavy load:

InvalidRead
 IMM_FreeThreadData:233
 DllMain:382
 __wine_spec_dll_entry:40
 MODULE_InitDLL:911
 LdrShutdownThread:2174
 call_thread_func:403
 start_thread:444

It kind of feels like a race between thread shutdown and process shutdown.
Does that ring a bell with anyone?
