OK. I installed this and am running it from a cron job, with an
expiration of 15 minutes. It seems to work fine. I note two things,
though. Firstly, it appears that there might be a race condition in
the time checking/saving code that could cause a message to slip through
the cracks and not generate a notification. Secondly, there is only one
notification timestamp file to record when the last run is. It would be
nice to be able to specify it on the command line, that way I can run
multiple versions in order to generate, for example, a 15m warning, a 4h
warning, and a 3d warning.
Before I get too far into proving a race condition and writing around
this, has this issue come up before?
