this answer probably doesn't help as i do not know the gvSIG code,
and is more of a note:
I think for mrsid code created images in a temporary sub folder of oj.
Processing in sextante also writes rasters to a folder. For intermediate
results these are deleted (if the code is written), but final processing
results are stored in windows temp (and the user needs to clean them
up). Though... ECW may work completely differently

All the data continuously generated in your IT infrastructure contains a
definitive record of customers, application performance, security
threats, fraudulent activity and more. Splunk takes this data and makes
sense of it. Business sense. IT sense. Common sense.
