It seems that you could discuss that, at least on RTEMS, the scan

the EPICS scan threads do not call directly into the network stack, and
their periodicity should perhaps not be disturbed by network loading.
Good point.
This would make the scan threads applicable to harder real-time
applications -- assuming that the iocsh thread priority was reduced,
too.
Of course the issue of starvation of network/iocsh threads again arises.
This is tricky stuff....
