Just to clarify about 2.6. 2.6 is supposed to have a short-lived
"unstable" state, where we implement fixes for the few problems on the
2.5 branch which require breaking the ABI. So, removing kernel-space
threads for other skins than RTDM is not the plan. However, does it
really matter whether other skins than RTDM use kernel-space threads for
changing the way kernel-space threads stacks are allocated?
