[Scons-users] Automatic Retry

[Robert Zeigler]

We've run into a similar issue, where there is a somewhat buggy version 
of an absolutely necessary tool.  98% of the time, it works fine. 
Sometimes, when processing large files and paging to disk, it crashes. 
In our case, we already override the slurm_spawn function for other 
purposes, and all of our tasks supply custom environments. So we added a 
"MAX_RETRIES" environment variable that the spawn function examines to 
determine how many times to rety a failed task.

Best,

Robert
