Thanks for the suggestion David. Unfortunately this approach doesn't work
for me because I'm trying to guard against the worst-possible scenario --
failure that affects an entire box (disk failure for instance). In that
case I want mod_jserv to redirect traffic to a JVM running on a different
machine, with minimal interruption of service.
