[syslog-ng]syslog-ng doesn't properly close file sources?

On NetBSD, it appears that only one process is allowed to open /dev/klog
at a time.  So syslog-ng gets a "device busy" error when reinitializing,
since it still has the file open under a different (though soon to be
closed) fd.  That's also why it worked fine with regular files when I
was testing earlier: they didn't care if they were opened twice.

I installed scsh-0.6.0 (and scheme48-0.57 just to be on the safe side,
though I don't think that was necessary), but I'm having problems trying
to regenerate affile.c.x.  make_class uses some unusual #! escapes which
don't behave under NetBSD, so I tried using "scsh -s make_class", but that
didn't work for me either:

 $ pwd
 /usr/local/src/syslog-ng-1.5.14/src
 $ cp /pkg/libol-0.3.1/bin/make_class .
 $ scsh -s ./make_class < affile.c > affile.c.x

BTW, here's what happens with make class:

$ uname -s -r
NetBSD 1.5.2

$ head /usr/local/bin/make_class
#!  \
-e main -s
!#
