 Does the machine have a wired network port? The trick I use on my 
 Kirkwood machines (love those gigabit ports) is to use nbd for 
 /var/lib/mock and swap, with zram swap set to 1/2 the physical memory. 
 With nbd backed by my storage box (13 SATA disks, ZFS), the disk I/O 
 performance for intensive tasks such as mock building has improved by 
 several orders of magnitude compared to even the fastest available SD 
 cards when it comes to random-write I/O. That should cure your OOM 
 without crippling the performance or killing your flash.
