This is not specifically directed at Laurent:
I just realised that the terminology that I'm using might be a bit 
confusing. I'm not talking about a surface triangulation of a higher genus 
object, but rather of a tetrahedralisation of a 3d object with higher 
genus.

I already use the 'tagging' technique in another context, so I am familiar 
with the idea. Maybe I do not understand you well, but I do not see an 
easy way to detect and fill up the holes in the tetrahedralisations that I 
load, with real tets. The holes can have non-convex shapes.
