I really like the idea of being able to log the rollouts, but I'm a
bit doubtful about the use of syslog() to do it.  It's not particularly
portable; on a multiuser system, there's a good chance the user won't
have even have permission to read it; and it introduces yet another
file format, which makes it tedious to write other programs to process
the logged output.

How about we add some sort of command like "set rollout log <file>", and
then write the results of the rollout to the specified file (if there is
one) in SGF format as we go?  SGF can already handle most of the important
data, and if we want to log other information that comes up we could either
dump it to a C[] property or invent another random property to hold it.

Cheers,
Gary.
