===Business Models===
 +
Some business models identified by me:
 +
* Marketing instrument (brand awareness, capabilities).
 +
* Enabler for other products (server software, hardware, solutions, consulting, service, support, books).
 +
* Free only for consumers, commercials need to pay.
 +
 
 +
==Notes==
 +
* "pthread_exit" and its relationship to process termination  ...
 +
** "atexit" actually gets called by the last thread in a process
 +
** "pthread_exit" in "main" would actually be perfect, if it was allowing to pass another return value than zero ...
