One way or another, yes.  We have several options, but the nicest one
requires changes outside of RCU, so cannot be carried out in time for the
upcoming merge window.  If that fails, we have other less-nice options
that -can- be confined to RCU, at least in the short term.

But one way or another, the issue that Sebastian raised will be resolved.

							Thanx, Paul
