And in addition parallelization with >multiple processes is very ugly to program. Threads and processes and different use cases. Tightly coupled data processing would be better using threads. OTOH something that eg has to act as a TCP user connection server such as sshd is better off with seperate processes. Of course if its something like a web server where a browser may initiate dozens of transient connections a second the smaller creation and resourse allocation footprint of threads works better.
