Need some expert help. I have a system that is hung hard, and I was
able to get it into gdb. From show_vmstat I see:

(kgdb-amd64-7.4-95) show_vmstat
SYSTEM MEMORY INFORMATION:
mem_wire:         285970432 (    272MB) Wired: disabled for paging out

-------------- ------------ ----------- ------
mem_total:   =    766435328 (    730MB)     Total memory

What is this telling me?
