[cvsnt] out of memory; can not reallocate

[bwhicks at aep.com]

Here's yet more info.

A bunch of 1 meg files (random text) committed till the RCS file reaches 
350 megs is fine. A single committed 350 meg file makes windows barf, but 
linux is fine. A 650 meg file is fine on linux. A 1.3 gig file was bigger 
than would fit into my laptop's RAM and my client barfed. 

Can someone help? Why is the behavior on windows different than on linux?

Thanks...

Brian
