Hm this is getting a bit too much I think, usually we create a new usigned
flags and a pile of bitmask defines for this. Then you have checks like

	if (flags & TEST_USE_ATOMIC_COMMIT)

or	if (flags & TEST_TYPE1)

or similar. A long list of various bool arguments is pretty hard to read
on the caller side, since no one can remember what 0/true/false stands for
in each case, and it's easy to screw up.

Looks all good to me otherwise.
