Passing TCP socket descriptors around

In linux, normally, it is impossible to "bind()" to the same TCP port twice. If you try to bind to the same port from second proces unix processes you'll see:

socket.error: [Errno 98] Address already in use

	* DJBX33A (Daniel J. Bernstein, Times 33 with Addition)
	*
	* This is Daniel J. Bernstein's popular `times 33' hash function as
	* posted by him years ago on comp.lang.c. It basically uses a function
	* like ``hash(i) = hash(i-1) * 33 + str[i]''. This is one of the best
	* known hash functions for strings. Because it is both computed very
	* fast and distributes very well.

	* Only the releases of the stable versions are listed in principle. The releases of the unstable versions especially considered to be important are indicated as "not stable."
	* The branches used as the source of each releases are specified, and the branching timing of them are also shown. BTW, before subversionizing of the repository, the term called "trunk" was not used, but this list uses it in order to avoid confusion.
	* In order to show a historical backdrop, big conferences (RubyKaigi, RubyConf and Euruko) are also listed. About the venues of such conferences, general English notations are adopted, in my hope.
	* ruby_1_8_7 branch was recut from v1_8_7 tag after the 1.8.7 release because of an accident.
	* 1.2.1 release was canceled once, and the 2nd release called "repack" was performed. Although there were other examples similar to this, since the re-releases were performed during the same day, it does not write clearly in particular.
