Comment:

 is there a way to count number of vertices? that is masked in the v.info
 -t output. So I'm not sure how it compares, but here I tried:

 {{{
 g.region rast=elevation.dem
 r.to.vect in=elevation.dem out=elev_dem feature=area -s -v

 v.info -t elev_dem
 nodes=523820
 points=0
 lines=0
 boundaries=523819
 centroids=246961
 areas=246961
 islands=1
 faces=0
 kernels=0
 primitives=770780
 map3d=0

 du -sh vector/elev_dem
 50M
 }}}

 it was slow & used a huge amount of memory, but it didn't crash.

 (g65, amd64, debian/lenny)


 some wxVdigit notes:
  - chosen map name box on left not wide enough
  - digitize points and move vertex buttons remain depressed.
    after clicking on extra tools menu, that button stays depressed as
 well.
  - memory from top: VIRT 1775m, RES 1.3g,  SHR 28m  python
  - it is slow but functional when zoomed in.
    when zoomed to full extent of map it pegs my local eth0, CPU (Xorg +
 ssh) near 100% for 10 minutes (& counting) while it attempts to redraw.
 (session tunneled over ssh to the machine  down the hall with 8gig RAM)
