R devel - Dec 2006 - empty pages in xyplot (2.4.0)

In 2.4.0 (and SVN) I am seeing xyplot creating empty pages for high page 
counts in layout - contrary to the manual which says high page counts should 
not matter. Everything works fine in 2.3.1.

library("lattice")
A<-data.frame(x=1:10, y=sin(1:10), z=round(1:10/3))
xyplot(x~y|z, A, layout=c(1,1,10))

The snippet above produces a valid plot in R 2.3.1, while in 2.4.0 and later I 
see a blank page with "x" and "y" letters on it.

Can anyone else reproduce this ?

                     thank you very much !

Yes. I will update the manual (but probably not in 2.4.1 as this
doesn't seem very critical) and in the longer run, perhaps add some
settings to control what should happen.
