What do you mean with defragmenting?  I think you mean joining freed
regions, which should be done at the time it is freed.  I always
thought that was the case already.

For the other changes I will wait for the comments of Okuji, he wrote
the old code.  But it always works on the PPC and x86, it sounds like
a 64 bits problem to me...
