comment GeoDirection and GeoDistance Memory Leaks: How to Recover the Memory?
No, the problem is in the Geo functions, they have the memoization problem.

It is not a memory leak, it is a memoization problem.

comment Histograms with pre-counted data
So, your example data could be of this form: Tally[RandomInteger[1000, 1000000]]?

And with a Flatten you get the simple positions.

comment How to make a 3D globe?
To avoid the strange spirals I used: Texture[Rasterize[pic, ImageSize -> 1500]] instead of Show in Mark's code.

comment Trying to prove that $x\sin(\frac{\pi}{x})\ge\pi \cos(\frac{\pi}{x})$ for $x\ge 1$
I know it is not rigorous but I think Taylor series are good as an aproximation of results. Ideally you should use the infinite terms in series.

comment SIGSEGV error with 3D Plots
I use CentOS 5 and Fedora 15 & 16. With CentOS I had the same problem but only with graphics with many points. In Fedora 15 it always crash, but in Fedora 16 it doesn't. I tried with M7, M8, and M8.0.4. Updating from 8.0.1 to 8.0.4 doesn't help. Problem is not M but the system.

Maybe it works like the Overlaps option: StringPosition["archbishop", altelem, Overlaps -> All].

comment How to generally match, unify and merge patterns?
@celtschk Yes, you are right, what I meant was a PatternUnion that simplifies too, simple union and intersection might be done using || (or Alternatives) or && as you showed. But like Union (which merges the list and delete duplicates) that function should simplify too. Interesting problem.
