Why not fix the libc code on those platforms so it does basic sanity
checking on the socket, and re-opens the socket when it discovers that
its cached filehandle for /dev/log is invalid?  I encountered this on
NetBSD and it was an easy library fix (it's patched in all current
releases (1.5.3 and 1.6 candidates) - what OS are you using?
