To run CMD check on MASS you need to set R_NSIZE in the environment.
500k should do.  MASS passes here on Solaris, Linux and Windows, if one
is patient enough.  I will point out that information is in the on-line
R complements, page 11.

I have just tried nlme on linux and 0.99.0 and example(nlme.formula)
does fail there in CMD check, eventually.

What MASS does not do is make a PDF manual, and that is mainly due to 
problems with the definitions of what needs to be escaped in the 
.Rd files.  A new version will follow once that is resolved
(which may need 1.0.0).

Um, looks like nlsList is not failing gracefully when memory is exhausted,
presumably because restart is in use.
