The main problem you'll run into is dustmite removing a load 
bearing element of the error and turning one OOM into another 
OOM. This can be partially mitigated by running dmd with "-v" and 
grepping for the last line in the ordinary failing dmd output, to 
ensure it gets "at least that far."

Dustmite is not a magical cure-all. Like any tool, it needs some 
investment of effort to use it fully, and there's tasks it's less 
good at. But reducing ooms with dustmite is certainly possible.
