I wonder why you guys are so hung up with threads. Real UNIX never had any

the truth.
Do you mean:
a. fork()ing programs do not crash?
b. The fact that a few programs are buggy is enough to ridicule
threads entirely?
What do you mean by "Real UNIX"? POSIX - an IEEE standard for Unix
operating systems - has a standard for threads. Does that mean POSIX
is not "Real UNIX"?
It is a theoretical concept not used much practically. sticky is often used
in the context of CVS tags.
Hmm. Ever looked at ls -ld /tmp ? In fact, I don't remember ever
encountering sticky bit in the context of CVS. Maybe you are confused
between the sticky bit and the setuid/setgid bits?
recursion is a theoretical concept not used much in practice.
Can you spell DNS??
I know that perl supports some bidirectional pipe using two
pipes,maybe u r talking some advanced stuff I dont know. But pipes have
always been unidirectional. If there are
POSIX specifies a pipe(2) system call for bidirectional pipes.
Implementations might choose a pair of unidirectional pipes, but that
is irrelevant.
