First of all great to see these patches. I have tested some values

I have set various values for $jobstartblocktime, (0 --> 20), but i did 
not see any slow down in qstat. The load on this test system is not huge.

Must i specify an option to pbs_mom to enable restart the jobs. like 
'-p' or must it work out of the box. I have tried it without options and
the jobs get restarted and an interactive job is killed.

With the '-p' option:
  - Interactive job will be killed
  - an job is not restarted
