workaround:

use m.proj (or just cs2cs, which m.proj is a front-end for) to reproject
the data and then v.in.ascii to import the data into the target
location.

you can even pipe things:

# assume LL WGS84 input, "tr" and fs= as needed
cat xyz.txt | m.proj -i | v.in.ascii -bt out=xyz_proj

no idea if there is any memory bottlenecks using that method.
