[torquedev] Rerunable jobs not restarting when nodes reboot

[Victor Gregorio]

Hello all, 

I have found that with Torque versions >= 2.1.10, rerunable jobs are not
restarting after the execution nodes reboot.  Torque version 2.1.9 works
as expected: rerunable jobs restart from the beginning after execution
nodes are rebooted.

Here is the [torqueusers] thread on the issue:
http://www.supercluster.org/pipermail/torqueusers/2009-April/008945.html

I am not certain why, but if I remove this patch (below) from 2.1.10,
rerunable jobs begin to restart properly after the execution nodes
reboot.  Please note that this patch was introduced in 2.1.10.

This is the SVN log for the patch:

Unfortunately, removing this patch does not fix the problem in 2.3.6.
Thoughts?
