How to create an idependent child procees on Win32 so parent:

1. after spawning child could continue without blocking and not waiting  
for child to exit
2. could kill new process
3. get notified when child exits

What is the best way to do this in Ruby? Should I use ‘fork’? How parent  
can be notified about child exit? Any examples I can look at?

Sorry if I am asking questions belonging to some FAQ, maybe I wasn’t  
researching this long enough, but I have very little time to find  
answers these days ☹

Thanks!  
Dima

Take a look at Daniel B.'s win32-process library. Find it at:
