FreeBSD's malloc(3) recycles its memory address space if it can.  Don't 
free(3) the memory region and try again... if you have enough 
swap/memory.  I didn't read your bulldozer summary completely so take 
my suggestion with a grain of salt.

Have you considered using boehm?  Last I checked it was reasonably 
smart about preventing/handling fragmentation.
