From a BusyBox shell I can run commands in the background. For example, 'calc &' runs the calculator and returns me to the shell prompt. From that shell prompt I can run other commands, including BusyBox applets like ls and 'expr $!'. However, if I try to run a shell builtin command, like pwd or 'echo $!' the shell blocks until the background command has terminated.
