Use on OS X.

Turns out this does only partially work on OS X. Here is how libuv for NodeJS implements it: https://github.com/libuv/libuv/blob/v1.x/src/unix/darwin-proctitle.c

You can easily strip away all these annoying deopen()/dlclose() calls by just including the proper header and linking using the -framework ApplicationServices compiler flag.

Kind regards, Ingwie!
