cache exiting from a simulation

[duncan]

While running a simulation (revision 2150) I got the following error;

Traceback (most recent call last):
  File "I:\production\gippsland_2005\run_gippsland2.py", line 97, in ?

    ,verbose = False
  File "I:\inundation\caching\caching.py", line 359, in cache
    funcname, dependencies, compression)
  File "I:\inundation\caching\caching.py", line 1072, in save_results_
to_cache
    mysave(T,datafile,compression)  # Save data to cache
  File "I:\inundation\caching\caching.py", line 1268, in mysave
    raise MemoryError, msg
MemoryError: ****WARNING (caching.py): Could not pickle data for compr
ession. Try using compression = False

This should continue, without caching, rather than exiting. (But still give the warning)
