[R] nlme, grid, lattice: Time mistery

This is rw140 on windows 98 (version compiled by Prof Ripley), grid and 
precompiled from CRAN and nlme compiled by me, all latests versions.

I have a groupedData object papas, and want a summary plot.

plot(papas) is fast but rather uninteresting.
plot(papas, outer=TRUE, aspect="fill") takes about 45 minutes (if it 
doesnt  hang R)
plot(papas, outer=TRUE, key=FALSE, aspect="fill") is again fast.

Why the immense time difference apparently caused by the 
key= argument? (this is a 64MB ram pentium III)
