Editing Fork (system call) (section)

===Clone===
<code>clone</code> is a system call in the [[Linux kernel]] that creates a child process that may share parts of its execution [[context (computing)|context]] with the parent. Like FreeBSD's rfork and IRIX's sproc, Linux's clone was inspired by Plan 9's rfork and can be used to implement threads (though application programmers will typically use a higher-level interface such as [[pthreads]], implemented on top of clone). The "separate stacks" feature from Plan 9 and IRIX has been omitted because (according to [[Linus Torvalds]]) it causes too much overhead.<ref name="opensources">{{cite encyclopedia |title=The Linux edge |first=Linus |last=Torvalds |encyclopedia=Open Sources: Voices from the Open Source Revolution |year=1999 |publisher=O'Reilly |url=https://archive.org/details/isbn_9781565925823 |isbn=978-1-56592-582-3 |url-access=registration }}</ref>
