Hi Enrico,

It depends on your definition of 'better' ;) (i.e. whether you're after
speed or minimal memory usage).  It also depends on your particular
usage patterns.  If you had blocks that became very large and then
shrank to become very small, you might end up using a lot more memory
than you need.

It's certainly worth trying the memcpy+malloc+free listed earlier.  Then
measure it and see if it's actually a problem on your particular setup.
The couple of times I've done this, it has turned out to be negligable.
