are you sure about this? I've written quite simple program (yet too long to paste here) which creates 40 pthreads, performs vfork in each of them, and exec if pid=0 in each child process, performing 2x sleep(1) between vfork and exec, and logging each step. I can see in logs, that all vforks are batched together, then come all "midsteps" and then all execs. The only explanation I see to this is that other pthreads are not paused when vfork is called.

Yes, it is correct. Your test code contains actions that you don't fully understand, in particular how sleep() is implemented.
