[TYPO3-dam] Indexing scales not good enough

[Jonas Dübi]

Hello Everyone

If you index a lot of files, I'm talking about some gigabites and some 
thousand files you allways run out of memory because the indexing 
functions/classes/exensions don't free theyr unused data.

I didn't find all the spots you have to look at yet, but I'll have to do 
that.

Important is, that you realy should take care of cleaning unused data 
out of the memory, to allow the indexing process to scale properly...

Regards Jonas
