Doing the full start of named.
The I/O err in isc_lex_gettoken() appears only triggered when getc()
hits EOF. ktrace is a little tough to get through with all the
threads. But the thread that logs that error tracing back from that
error being sent out a fd does stuff that looks like prepping for
syslog like getpid, and then (priorly; working backward) read()'s the
file apparently just peachy.
RET read 228/0xe4
% wc empty.db
11 38 228 empty.db
and the text reads just fine. So something is getting squirreled up
above the syscall level.
