execution-time

I'm implementing a checking system in Ruby. It runs executables with different tests. If the solution is not correct, it can take forever for it to finish with certain hard tests. That's why I want to limit the execution time to 5 seconds.

I'm using system() function to run executables:

system("./solution");

.NET has a great WaitForExit() method, what about Ruby?.

Is there a way to limit external process' execution time to 5 seconds?

Thanks
