syslogd AFAIK is not multithreaded. Therefore the issue of thread safety
doesn't arise.

As far as syslog(3) is concerned, it works over sockets and therefore
should be safe to use from a multithreaded program. Read the sources
for a definitive answer.

With most distributions, there is a log rotation facility, run as a 
cron job. Perhaps you can enhance the cron job to back up.

Many - lookup in freshmeat.net. Also read the LIH archives - there was
some discussion about a perl script that did log coloring.
