We now specify intrins as separate DAPS lines. This syntax is much
nicer and well-grouped than the previous negtrin-*/postrin-* param
names.
Alas, we're about to replace it in the next few commits already though.
We use io_uring_register_buffers() for IoUringAssemblyEngine instead
of using mlock(). This __appears__ to have reduced CPU utilization on
the Dell laptop. Could also be that we recently upgraded total RAM
from 8GiB to 32GiB.
We now allocate all the stimFrames for a StimBuffer using a
single StagingBuffer. This gives us all the benefits we're
looking for (pinning, alignment, etc).
