When a process is created using vfork() child process is created and starts running in the parent process address space, until exit() or exec() is called.

What happens to the parent process, if some one kills the child process before calling the exit()/exec()?

Lets assume I have a system with RAM of 1GB. and virtual memory is 500MB. That brings to 1.5GB i.e. 1500 MBytes.

I have read somewhere that when I process is created stack of 8MB is associated to that process. So, assuming that any of the process is not allocating any dynamic memory or anything, then does it mean that, Maximum number of process that i can create is 1500/8 and i.e. 187 Process.

Please clarify my understanding,
