For historical reasons (NMesh was supposed to be wrapped in a Python
module called Mesh) the NMesh getter function is called GetRaw.

Not precisely.. GetRaw() will still return a list of NMesh objects.
Those are just wrappers, though, and shouldn't consume much memory.

AFAIK there's no way to get just the names. The Python objects Object,
NMesh and so on don't require very much memory by themselves, until one
uses them to actually work on the data. To conserve memory, remove your
references to each object after processing it, i.e. instead of:

for mesh in Blender.NMesh.GetRaw():
  do_something(mesh)

you may want to:

meshes=Blender.NMesh.GetRaw()
while meshes:
  mesh=meshes.pop(0)
  do_something(mesh)

Remove the 0 for reverse order. This way you'll only have one
non-pristine NMesh object around. I rather doubt you'll need this level
of tricks though.
