In this case, t= he foreground process is sleep and it does not exit on SIGINT because the signal is only sent to the shell. Depending on order of events, this could cause the SIGINT to be unexpectedly ignored. On lightly loaded bare metal, the chance of this happening tends to be le= ss than 0.01% but with higher loads and/or virtualization it becomes more likely. Starting the sleep in background and using the wait builtin ensures SIGINT will not be ignored.
