[R] GAM Package: preplot.gam taking a **long** time

Hi: I have a large data set that I'm testing and I'm finding that
preplot.gam is taking a very long amount of time to compute (like, more
than 20 minutes). My machine is 32-bit, Debian unstable, 4GB memory,
dual Xeon 3GHz. While the data set is very large, the gam() procedure is
able to compute the model without any trouble, in a minute or so. Is
there any reason why preplot.gam would be so slow? I am not using
"newdata" in the preplot.gam function, so I am assuming that the memory
is not a problem. Or could it be?
Is it normal for preplot.gam to take so long on large data sets? I have
not had this experience with S-Plus, on a lower quality machine, same data.
