#1802: DiskFile and RAM usage

 Priority:  P3          |   Milestone:  CPS 3.4.4   
Component:  CPSSchemas  |     Version:  TRUNK       
 Severity:  minor       |    Keywords:  DiskFile RAM
------------------------+---------------------------------------------------
 While working on #1801, I noticed that way too much goes through Zope's
 RAM (if I got it right, of course):

   * a cut/copy/paste loads the file contents in memory. What happens for a
 folder holding hundreds of 10 MB files ?
   * before going to disk, the whole file is loaded in RAM. This can't work
 for really large files.

 One more thing: __str__ dumps the contents ! I didn't dare changing that,
 but I saw str(obj) being called in transaction/ZODB layers (for logging
 purposes, I think).
