Ok. I'll take out max_write() callback and only implement non-preemptive misc.max for EPC. I can also separate OOEPC_killing enclaves out, which is not needed if we only block allocation at limit, no need killing one enclave to make space for another. This will simplify a lot.
Thanks to all for your input!
