Fragmentation is bounded by the fundamental block size you do basic
allocations in. If you refuse to allocate small blocks in the 'n' last
large chunks, you place immovable blocks in the same chunk as much as you
can and you try to keep relocatable blocks together you sent a fundamental
bounding for fragmentation. Limiting the nature of relocatable blocks
gives you a CPU time bounding too.
Irix needs to hand out 64K blocks for the video at arbitary times and has
no problems..

And must not be exploitable by a user or remote user influenced events
triggering the wrong patterns of allocation.
