I'm pretty satisfied with avoiding paging by disabling swap and avoiding
scheduler-randomness by removing cores from the scheduler pool and
assigning them manually (linux boot isolcpus=... and taskset(8)). Calling
into the runtime system of a high level languages is an interesting nut
still to crack from my perspective :). t'would be especially amazing if it
were practical without needing a separate thread.
