History
Mark Johnston ccc5d6dd97 Use M_NEXTFIT in memguard(9). 
memguard(9) wants to avoid reuse of freed addresses for as long as
possible.  Previously it maintained a racily updated cursor which was
passed to vmem_xalloc(9) as the minimum address.  However, vmem will
not in general return the lowest free address in the arena, so this
trick only really works until the cursor has wrapped around the first
time.
