 |  This is because, once a node has been created, tmpfs needs to keep its id
 |  and generation number so that if the same node is reused it carries the same
 |  generation number.
 |  
 |  Maybe the memory needs could be lowered by keeping a id->gen map?  This
 |  way, when a node was deleted, tmpfs could insert this pair in the map for
 |  later reuses, avoiding the need to keep the whole node in memory.  The
 |  problem could not disappear completely (and it looks like it cannot), but it
 |  would take less memory.
 |  
 |  Does this sound reasonable?
 
 just keep a global generation number counter and use it to allocate generation
 numbers.
