Page faults and threads

[Mark Terribile]

Hi,

Can anyone tell me: when a thread hits a page fault in a multithread program on FreeBSD, is the entire program stopped waiting for the page to be loaded/made ready or just the one thread?

Has this changed in recent versions with the changes to the scheduler?

And, if you know, do other Open-Source OS's do the same thing, or are they all different?
