Comment (by hinder):

 I currently disable syncing of Formaline tarballs because they take up so
 much space and time.  This defeats the whole purpose of Formaline.  The
 proposed solution in the patch only eliminates duplicated data from within
 a single simulation.  In the case of running benchmarks, this does not
 help, as typically there will only be one restart per simulation.
 Similarly for small debugging runs.  The current solution is OK, but it
 would be much better if the files were shared across simulations.  They
 could live in the CACHE directory, just as executables do.  Is there a
 reason to treat them differently?  When rsyncing simulations, the CACHE
 directory could be synced as well, and with suitable options, rsync will
 respect the hard links.

 Regarding the code: it makes an assumption about the name of the output
 directories.  This should be obtained from a function which would be used
 throughout simfactory.  I know this assumption is made frequently, but for
 new code, we should try to do better.

 Please also see #127 if you think that simfactory 2 puts hardlinks to the
 executable in each restart.
