 Replying to [comment:2 hamish]:

 -t output.
 Only through v.build (XXX vertices registered) because the number of
 vertices is not stored in topo and every primitive must be read.
 So I'm not sure how it compares, but here I tried:

 It's partially slow and needs a huge amount of memory because topo keeps a
 list of updated features when opening a vector in update mode. This is
 unused and disabled in grass7, one effect is that vdigit in grass7 is a
 bit faster and uses less memory than in grass6.
