Previously, procfs would retrieve the rproc and rprocpub tables from
RS in two separate calls. This allowed for a race condition where the
tables could change in between the calls, resulting in a panic in
procfs under certain circumstances. RS now implements a new method
for getsysinfo that allows the retrieval of both tables at once.
