Camino does save the file periodically, and it uses "safe-saving", in
that it writes the new file to a side location then moves the file
onto the old location. This is about as much as a well-behaved
application can reasonably be expected to do; for any application to
really guarantee that everything is always on disk exactly as it
expects (given that HFS+ does not guarantee that no data will be lost
in the case of a power failure) would require frequent explicit
flushing of the disk cache. If every application did that the
performance of your system would be monumentally bad, in exchange for
a tiny reliability gain.
