Before starting a job, cron(8) will sleep a random number of seconds,

when a lot of jobs are to start at the beginning of a particular minute

e->cmd. free_entry() now does the right thing with
partially-initialized structures.
load_entry(): Don't call env_free() on e->envp throughout the routine
before jumping to eof; the free_entry() call at that label will take
care of it. The previous behavior resulted in e->envp being free'd
twice (well, the second time would usually result in a crash, but
that's besides the point); once in load_entry(), and once in
free_entry() after the former called the latter. Also note that the
check added to free_entry() (above) doesn't help, since e->envp wasn't
reset to NULL after env_free().
