951 /* This code can be executed from either of two paths: an explicit -

952 '{}' command, or via a function call. If we are executed via a -

953 function call, we have already taken care of the function being -

954 executed in the background (down there in execute_simple_command ()), -

955 and this command should *not* be marked as asynchronous. If we -

956 are executing a regular '{}' group command, and asynchronous == 1, -

957 we must want to execute the whole command in the background, so we -

958 need a subshell, and we want the stuff executed in that subshell -

959 (this group command) to be executed in the foreground of that -

960 subshell (i.e. there will not be *another* subshell forked). -

961 -

962 What we do is to force a subshell if asynchronous, and then call -

963 execute_command_internal again with asynchronous still set to 1, -

964 but with the original group command, so the printed command will -

965 look right. -

966 -

967 The code above that handles forking off subshells will note that -

968 both subshell and async are on, and turn off async in the child -

969 after forking the subshell (but leave async set in the parent, so -

970 the normal call to describe_pid is made). This turning off -

971 async is *crucial*; if it is not done, this will fall into an -

972 infinite loop of executions through this spot in subshell after -

973 subshell until the process limit is exhausted. */ -
