I'm working on cleaning up the reports from shell COM things, and I can still see these leak reports:

Error #6: LEAK 12 direct bytes 0x0031a1b0-0x0031a1bc + 0 indirect bytes
0x77a91862 <ntdll.dll+0x51862> ntdll.dll!LdrpSearchResourceSection_U

Error #7: LEAK 8 direct bytes 0x0031b818-0x0031b820 + 0 indirect bytes
0x77a9179e <ntdll.dll+0x5179e> ntdll.dll!RtlpUpdateTEBLanguage

It looks like a second thread is created and setupapi.dll!_CRT_INIT gets called to initialize some thread local structures, but somehow they aren't eventually freed. I can use windbg to break on RtlpUpdateTEBLanguage and then add watchpoints on the object root. This needs further investigation to see who is supposed to be freeing it that isn't. For now I think these are true leaks that occur once per thread created this way. Only I'm not sure how exactly the thread is getting created, or I would try to create a minimal test case.

I'm going to split this out, file it separately, and add a suppression.
