From: Jack Steiner It looks like the call to sched_balance_exec() from do_execve() is in the wrong spot. The code calls sched_balance_exec() before determining whether "filename" actually exists. In many cases, users have several entries in $PATH. If a full path name is not specified on the 'exec" call, the library code iterates thru the files in the PATH list until it finds the program. This can result is numerous migrations of the parent process before the program is actually found.
