[Harald Barth]

> krenew -t -- /path/to/long/running/job

Or the same functionality as provided with Heimdal's kinit.

SYNOPSIS
     kinit ...
...
           [principal [command]]

...
     If  a command is given, kinit will set up new credentials caches, and AFS
     PAG, and then run the given command.  When it finishes the credentials
     will be removed.
...

(Heimdal, the package that always has the functionality but hiding it well)
