These are all on x86-64. You'll get slightly different results on a 32
bit arch.
Largest structures, by size:
qemud_vm_def: 16608 4
qemud_vm_os_def: 16436 1
_testConn: 14504 2
qemud_vm: 12368 2
qemud_network: 8240 0
qemud_vm_disk_def: 4376 2
qemud_driver: 4192 1
qemud_vm_net_def: 4136 2
xenXMConfCache: 4112 0
Hmm, practically all of those large structs come from the statically
allocated char arrays of PATH_MAX. Switching them to be malloc'd would
save far more than packing the structs.
