comment Algorithm to find N nearest points to point
+1 for k-d tree. I don't know about Java implementations, but the Python/C implementation in scipy.spatial.cKDTree is insanely fast, ever for 100 nearest neighbors to a couple hundred thousand points.

comment What is the purpose of arcpy.Array()?
I think @crmackey is right. You can see this in the source of the Array() class in C:\Program Files (x86)\ArcGIS\Desktop10.1\arcpy\arcpy\arcobjects\arcobjects.py and the ArrayMixin() class in C:\Program Files (x86)\ArcGIS\Desktop10.1\arcpy\arcpy\arcobjects\mixins.py (replacing 10.1 with whatever version you have).

comment Cutting a circular buffer via Arcpy
@EmilBrundage Nice script! One alternative for ArcGIS 10.2+ is to use the buffer() and cut() methods of the arcpy.Polygon class to perform the geometry operations instead of using geoprocessing tools. This shouldn't affect the output, but it is probably faster.

comment Directional Spatial Join with Python - Arcpy
Do you want to join the centroid to the closest polyline along each of those exact bearings? Or just in each quadrant?

comment Create Complex Polygon from Point Layer using only Boundary Points in ArcGIS
What you want is a concave hull, which is not natively available in ArcGIS, unlike convex hulls. If your point spacing is fairly small, you could use Euclidean Distance > Reclassify > Expand > Raster to Polygon or Aggregate Points.

comment ArcMap 'in_memory' trouble?
Good detective work. This is probably because in_memory datasets are treated like geodatabase feature classes, which (I now remember) cannot start with numbers.

comment ArcMap 'in_memory' trouble?
Have you tried running RasterToPolygon_Conversion() with output to an in_memory dataset in the ArcMap GUI? Some geoprocessing tools (e.g. project) don't allow outputting to in_memory datasets.
