This is not remotely true. For a long time I had the normal pbs_sched 
You just have to alter a couple of configure options to prevent it from 
The built-in scheduling iteration is set too low; starting with

#> pbs_sched -a 600


Furthermore you should set (via qmgr)

set server job_stat_rate = 120
set server poll_jobs = True

For many jobs you really should consider maui, though - it's far more 
efficient in scheduling.
