I believe, however, that Doug Rabson was replacing the stubbed routines in the NFS case to respect the lock used by vclean. This is a sort of kludge soloution, but should fix the NFS vnode problems. The paging problems were mentioned by John Dyson as something he was actively looking at; they are, it seems, related to the VM object alising issues that the Lite2 unionfs also suffers under (from my minimal reading of John's posting and the affected code in both FS's). > I'm sorry about not being more up-to-date on this; I've been INSANELY busy > the last few weeks, and haven't had time to dig into the NFS layer.

I believe the work discussed above may be sufficient to mask both these problems (and solve them, in one of the cases).
