Try setting:
map.buffer_size = 256 # some number greater that at half your tile
size usually helps
also potentially could help in general to displace the text labels
away from the points:
dx = 0
dy = 5
textsym.displacment(dx,dy)

I'm trying that, but it doesn't seem to change the rendering.
I'm doing this in Python. Here is a code snippet:
textsym = mapnik.TextSymbolizer(
'ID',
'DejaVu Sans Book',
10,
mapnik.Color('#000000')
)
textsym.halo_fill = mapnik.Color('#FFFFFF')
textsym.halo_radius = 1
textsym.allow_overlap = True
textsym.avoid_edges = False
rule.symbols.append(textsym)

More info...it turns out to have nothing to do with the slashes.
The text is not being rendered because it overlaps the edge of the
tile. Is there any way to force partial rendering up to the tile
edge?

Subject: [Mapnik-users] Slashes in TextSymbolizer Text?
I'm using a TextSymbolizer to add labels to the icons I'm rendering
with PointSymbolizer.
Each point in my shapefile has an attribute ("ID") and the
TextSymbolizer is configured to render this field.
Most of the points have IDs of the format "XYZ", and these are
rendered correctly. However, a minority of points have IDs of the
format "ABC/XYZ", and for these, the text isn't rendered (the icon
image is rendered alone).
Are forward slashes not allowed in shapefile field values that are
to be rendered as text labels?
