[ looks ... ] Yeah, there's no mention of KeepAlive in 10.4's
launchd.plist man page. It does have a convenient example
saying that OnDemand = false does what we want:
The following XML Property List simply keeps "exampled" running continu-
ously:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC -//Apple Computer//DTD PLIST 1.0//EN
http://www.apple.com/DTDs/PropertyList-1.0.dtd >
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.example.exampled</string>
<key>ProgramArguments</key>
<array>
<string>exampled</string>
</array>
<key>OnDemand</key>
<false/>
</dict>
</plist>

I'd just drop them into files in the data directory; we're still going
to recommend that people use the logging_collector, so this is just a
stopgap to collect startup errors.
