 \ Allocator struct
 
+\ TODO: add the concept of "max allocation unit" to abort when we're allocating
+\ chunks that are too big. I got burned while working on asm/uxntal.c, chasing
+\ what I thought was a tricky memory corruption bug, but it just so happened
+\ that the Macro struct at the time was more than ARENASZ and that made memory
+\ silently outstep its bounds.
