You didn't include libc in this analysis.  The ONC RPC runtime uses
select inside its service handling code
(/usr/src/lib/libc/rpc/svc_run.c:svc_run()).

This causes problems if the calling program increases FD_SETSIZE and its
file descriptor process limit, and then expects high-numbered file
descriptors to work properly with the RPC runtime's built-in small
fd_sets.  To make it worse, the RPC runtime exports its fd_set as a
global symbol the program can tweak.  All callers had better use the
same set size!
