hello.on linux we will see a new domino server process/thread is created for each
client.how does linux do this?does it use pthread?using fork or clone or someway
else?what's the common way of linux to support apps like lotus domino that will
have lots of concurrent users which are served by seperate server process/thread?
regards

pthreads are modeled on top of the clone() system call.

Just go ahead and support it, I guess.

Well, in Linux there is no separate concept of threads, so each thread
is a separate process with it's own PID and the PPID of the main thread.
In fact pthread_create() sits just on top of clone().
The way each program handles multiple conections is up to the program,
for example apache 1.3 and below does a fork(), mozilla does a
pthread_create(), BOA does a select() in only one process, and apache
2.0 and up does both a fork() and pthread_create().
