This way we can call _endthreadex() at the end as stated in the documentation.
This will also simplify FreeLibrary()-safe implementation for UCRT.
thread_data->handle is not set on purpose, so that accidental _endthread() won't close it, see: existing tests.

What's the reason of unconditionally creating a suspended thread?

It's a leftover from initial copy-and-paste of the _beginthread()'s trampoline logic.
The thread there is suspended because _endthread() closes the handle, and we only get that after creation.
Here I was doing something simillar initially, but it turned out that even _endthread() should not close anything. I've changed a few things but forgot to change this part.
Revised version of the patch is attached, thanks.

The return -1 here is my bad, because I've misread MSDN, but looks like _beginthread() has a different behavior.
_beginthreadex() returns zero and is mentioned to set errno and _doserrno (I'll include that in next revision) whithout any details.
It would be nice to do similar changes in _beginthread() as well.
_beginthread() is documented to: * return -1L * set errno to EAGAIN in too many threads * EINVAL for invalid argument / stack size is incorrect * EACCESS if insufficient resources (e.g. memory)
I can clean it up a bit an make it more in line with what the spec says.
MSVCRT _beginthread[ex]() doesn't exhibit the same behavior.
Using ThreadExit() does leak the reference.
FreeLibraryAndExit() has to be used because the DLL may be the only user of the given CRT.

Any standard way to do that from DLLs? The current winetest_*() implementation is not really meant for this use case, as it defines all the function in testlist.c (#define STANDALONE) + adds a main() and requires winetest_testlist.
Thanks for the review :-)

- WaitForSingleObject(args->past_free, 100);
It doesn't matter that much in this case but please test WaitForSingleObject return value. It can still give some hints if tests start to fail.
Any standard way to do that from DLLs? The current winetest_*() implementation is not really meant for this use case, as it defines all the function in testlist.c (#define STANDALONE) + adds a main() and requires winetest_testlist.
I don't know, probably it's not worth to invent something here. How about changing the timeout to INFINITE then?
