My understanding is no, Condor should do this for you.

There is some text at the bottom this page (sec 6.1.2) -
  http://www.cs.wisc.edu/condor/manual/v7.4/6_1Linux.html

... but it looks like it could some updating (any suggestions? what 
would you like to see added such that it would have helped you out 
more?) re 64bit etc, and perhaps it would be better off moved to the 
manual section  on StandAlone Checkpointing (sec 4.2).
